What is Beurre Blanc?
Beurre blanc, which literally translates to “white butter” in French, is a luscious butter-based sauce that originated in the Loire Valley region of France. While not as renowned as hollandaise, this cream-colored sauce has earned its place in French cuisine, especially when it comes to dressing up seafood dishes.
At its core, beurre blanc is an emulsified butter sauce made from a reduction of dry white wine, vinegar (or lemon juice), and finely minced shallots. This aromatic base gets enriched and emulsified by whisking in generous amounts of whole butter off the heat to form a velvety, glossy sauce.
Despite its name’s suggestion, the color of a properly made beurre blanc is not stark white but rather a pale yellow hue from the butterfat emulsion. When prepared carefully to avoid separating, it has a lush, creamy texture that clings nicely to proteins like fish and veggies.
The flavor profile of beurre blanc is bright, delicate, and slightly acidic from the vinegar reduction. The shallots provide an underlying savory aromatic base. However, the sauce is not quite as rich or decadent as an egg-enriched hollandaise.
This balance of acidity, butteriness, and mild shallot notes makes beurre blanc an exceptionally versatile sauce for finishing sauteed dishes like seafood, poultry, and vegetables. Its elegant simplicity allows the natural flavors of the main ingredients to shine through.
How Beurre Blanc is Prepared
While the ingredients for beurre blanc are simple, the preparation requires careful technique to properly emulsify the butter into the sauce. Attention must be paid to control the temperature and ensure the butter is incorporated slowly to achieve that coveted smooth, velvety texture.
Making the Reduction
The process begins by making a reduction of the white wine, vinegar (or lemon juice) and minced shallots. These are combined in a saucepan and simmered over medium heat until nearly all the liquid has evaporated and just a couple tablespoons of concentrated syrup remain. This reduces the harsh acidic bite while intensifying the flavor.
Once reduced down enough to lightly coat the bottom of the pan, the heat is killed and the pan is removed from the burner; this is crucial to controlling the temperature for adding the butter successfully.
Mounting with Butter
With the reduction slightly cooled, whole butter is then gradually incorporated while vigorously whisking constantly. The butter is cut into small cubes and added a couple pieces at a time, allowing each addition to fully emulsify before adding more.
The residual heat in the reduction gently melts the butter, allowing it to disperse and emulsify into the sauce as you whisk. Overly hot temperatures can cause the sauce to break, so removing it from direct heat is key.
This slow, methodical process of whisking in butter continues until the full amount is seamlessly emulsified into a smooth, creamy, glossy sauce. The more butter is incorporated, the richer and thicker the beurre blanc becomes.
Finishing Touches
Once that lush, velvety emulsion is achieved, the beurre blanc can be seasoned to taste with salt, white pepper, herbs like tarragon, or even a touch of cream for added richness if desired. Some chefs strain out the shallots for a completely smooth sauce as well.
Properly made, a beurre blanc should have body and elegantly coat a spoon, but still remain quite fluid and pour easily at warm temperatures to nap over proteins and veggies. Serving it too hot can cause separation, so it’s best served gently warmed.
When done carefully with patience, beurre blanc achieves that luscious, buttery consistency that adds a refined touch to simply cooked dishes without overwhelming them.
What is Hollandaise sauce?
Hollandaise is arguably the queen of butter sauces and one of the five revered French “mother sauces.” This rich, velvety emulsion has reigned over brunch tables and elegant plates for centuries, thanks to its decadent taste and texture.
At its most basic, hollandaise is an emulsion of egg yolks and melted butter, typically seasoned with lemon juice, salt, and pepper. But this seemingly simple sauce is a testament to the transformative power of emulsification.
When properly executed, hollandaise takes on a lusciously thick, creamy consistency that clings to and smothers whatever it graces. It has an undeniably luxurious, indulgent richness from the butterfat emulsified into the bright, tart yolks.
Despite its intimidating reputation, hollandaise is surprisingly versatile. While inextricably linked to eggs Benedict and smothering poached eggs with that luscious lemony blanket, the sauce has traveled far beyond the breakfast realm.
Hollandaise’s rich body also makes it an ideal sauce for napping proteins like fish, veggies, and meats. Its bright tang can cut through richness, while the creamy texture adds an upscale touch.
The sauce is also a “mother” from which other derivatives spawn, like the tarragon and shallot-laced béarnaise for steak. Choron sauce builds on hollandaise’s eggy richness with tomato for an orangey hue.
How Hollandaise Sauce is Made
While hollandaise appears deceptively simple, the technique required to achieve that iconic, lush, velvety emulsion is quite delicate. It requires precision cooking and a deft hand to coax the egg yolks into smoothly binding with the butter.
Preparing the Egg Yolk Mixture
The process begins by separating the egg yolks from the whites completely. The yolks get placed in a heatproof bowl or the top pot of a double boiler to cool off. They are whisked together vigorously with lemon juice, water and seasonings like salt, white pepper or cayenne until fully incorporated.
This mixture then goes over a gently simmering water bath, constantly being whisked as it heats up gradually. The keys are using low, controlled heat and moving the bowl continuously to prevent any curdling or overcooking of the yolks.
Emulsifying with Butter
Once the yolk mixture becomes pale and thickens slightly, it’s time to start incorporating the butter. Some recipes call for using whole butter, while others use clarified butter, which has the milk solids removed.
Whether whole or clarified, the melted butter gets incorporated a small amount at a time while continuously whisking the yolk mixture vigorously. This gradual emulsification allows the fats and water to bind together into that coveted thick, velvety texture.
Only a small knob of butter goes in at first, fully whisking it in before adding more butter in a thin stream until it’s all smoothly incorporated. Whisking constantly is crucial to achieving that lush, uniform emulsion.
Temperature Control
The challenge lies in maintaining low enough heat that the yolks don’t scramble while keeping it warm enough that the butter incorporates properly. Too hot and it separates into a broken mess; too cool and it becomes dense and curdled.
Ideally, the hollandaise will thicken up to a luscious, pureed consistency that coats the back of a spoon. If it does separate, quickly whisking in a small splash of warm water can sometimes revive it.
Seasoning Options
Once that dreamy, velvety sauce is achieved, hollandaise can be finished with a few additional seasonings and flavors if desired. Nutmeg, cayenne, paprika or mustard powder can add hints of warmth. Herbs like parsley, tarragon, chervil or chives fold in nicely.
Serving hollandaise at the perfect body and consistency is best achieved by transferring it to an insulated container or bowl over warm (not hot) water to keep it in its emulsified, pourable state until ready to sauce plates.
Beurre Blanc Vs. Hollandaise Sauce
Base Ingredients
The main difference between beurre blanc and hollandaise lies in their base ingredients before butter is incorporated. This foundational distinction sets these sauces on very different paths from the start.
Beurre Blanc Base
The base of beurre blanc starts with a reduction of dry white wine, vinegar (or lemon juice) and shallots. These three ingredients are simmered together until they reduce down to just a couple tablespoons of concentrated liquid packed with sharpness from the vinegar and delicate shallot flavor.
This flavorful reduction becomes the backbone to which generous amounts of whole butter are then emulsified in to create the creamy, velvety sauce. Some variations include adding cream or chicken/fish stock to the reduction as well.
Hollandaise Base
In stark contrast, hollandaise sauce forgoes any wine or vinegar reduction. Instead, its base centers around egg yolks as the emulsifying agent. Egg yolks are vigorously whisked together with lemon juice, water, and seasonings like salt and cayenne over gentle heat.
This mixture is where the melted butter gradually gets incorporated and forms the famed thick, creamy emulsion that is hollandaise. The egg yolks provide richness and act as the binding force that allows the sauce to come together.
While both finished sauces achieve a luscious, creamy texture, their pathways start off on completely different notes based on these primary base ingredients. One is a vinegar-sharpened reduction, the other an egg-enriched emulsion. This divergence lays the foundation for their distinct flavors and best use cases.
Hollandaise as a “Mother Sauce”
In the hierarchy of French sauces, hollandaise stands tall as one of the leading “mother sauces” from which other well-known sauces take their inspiration. Its renowned status is thanks to its widespread use as well as its ability to serve as the basis for several other classical sauce variations.
The five mother sauces in French cuisine are: béchamel, velouté, espagnole, hollandaise, and tomato sauce. They are the sauces from which many other secondary sauces start, through the addition of different ingredients and flavoring components.
Hollandaise’s rich, creamy emulsion of egg yolks and butter provides a versatile starting point. Some of the notable sauces that stem from hollandaise include:
- Béarnaise: A version of hollandaise with added shallot, chervil, tarragon, and vinegar reduction for an herbaceous twist.
- Choron-HHollandaise with the addition of tomato purée, giving it an orangey hue.
- Mousseline: Hollandaise whipped together with melted butter and heavy cream for an even richer, fluffier texture.
- Sauce Maltaise: A hollandaise variation featuring orange zest and blood orange juice.
While not a mother sauce itself, beurre blanc is a distinct butter sauce without any derivatives branching off of its core preparation method. Its simple shallot, wine, and vinegar base is prized for complementing seafood and vegetables, but it is not as ubiquitous or widely used as hollandaise in French cuisine.
Texture and Consistency
While both beurre blanc and hollandaise achieve a luscious, creamy texture, there are some distinct differences in their viscosity and richness when properly executed.
Beurre Blanc Texture
A well-made beurre blanc has a velvety, pourable consistency. It should easily coat the back of a spoon but still be fluid enough to lazily run off the sides. The sauce appears glossy and only slightly thickened from the emulsified whole butter.
Beurre blanc relies primarily on the wine and shallot reduction for its flavor depth. The butter serves to enrich the sauce and create a creamy, emulsified texture without being quite as thick and lush as hollandaise. It has a more fluid, sauce-like consistency, making it ideal for napping and pooling.
Hollandaise Texture
In contrast, a classic hollandaise is much thicker and richer thanks to the emulsified egg yolks. When properly prepared, it has a creamy, velvety texture with a denser, more viscous consistency than beurre blanc.
A hollandaise should be thick enough to cling to and nap over items while still being silky smooth and pourable. It should form a lush, creamy coating rather than thinly saucing items. Overcooked or broken hollandaise will separate into a thin, greasy texture.
This thicker, more spoonable richness makes hollandaise well-suited for things like eggs Benedict, where you want that indulgent, clingy yolk-enriched sauce. The density allows it to deliciously smother breakfast items.
So while both are creamy French sauces, beurre blanc errs on the side of a pourable, lighter cream, while hollandaise aims for a more lasciviously thick and decadent consistency. Two distinct tactile experiences are built from their differing ingredient bases.
FAQs
What dishes are beurre blanc and hollandaise best suited for?
Beurre blanc’s bright, acidic yet buttery flavor makes it an excellent sauce for simply prepared seafood like fish, scallops, and shrimp, as well as vegetables. Its fluidity allows it to nap and coat nicely. Hollandaise’s rich, thick texture is perfect for eggs Benedict and other brunch items. Its richness also complements proteins like steak, veggies, and fish.
Can you make these sauces ahead of time?
Both sauces are best served freshly made, as reheating can cause them to separate or break the emulsions. However, hollandaise can be kept warm for a short period in an insulated container with some warm water. Beurre blanc does not hold as well once made.
What causes a broken hollandaise or beurre blanc sauce?
In hollandaise, scrambled eggs or separation usually occur from letting the yolks get too hot during cooking. With beurre blanc, adding the butter too quickly or letting the reduction get too hot can break the emulsion.
Are there any shortcuts to making these sauces?
While it is possible to make “mock” versions with things like cream or milk instead of butter, the traditional methods ensure proper emulsified, luxurious textures. Using a blender can be riskier than whisking by hand and doesn’t allow enough control.
What are good flavor variations?
Hollandaise lends itself to additions like cayenne, herbs, or even béarnaise with tarragon and vinegar. Beurre blanc can have cream, chicken/fish stock, or herbs like tarragon folded in.
Can you use olive oil or vegetable oil instead of butter?
While olive oil or vegetable oil can technically create an emulsified “sauce”, butter is essential for achieving the proper rich flavor and texture of hollandaise and beurre blanc. Substitutions don’t work well.
How long can hollandaise and beurre blanc be stored?
Hollandaise can be kept warm over a double boiler or insulated container for 1-2 hours before the emulsion breaks down. Leftover hollandaise should be discarded. Beurre blanc doesn’t hold very well after cooking and is best used immediately.
What is the difference in calorie/fat content?
Hollandaise is significantly richer due to the egg yolks and high butter content. One serving can have 200+ calories and 20+ grams of fat. Beurre blanc is lighter, with around 100 calories and 10 grams of fat per serving from just the butter.
Can you freeze and reheat these sauces?
Neither sauce freezes very well. The emulsions will break when thawed and reheated, leaving you with a curdled, separated mess. They should be made fresh each time.
What tools are recommended for making them?
For hollandaise, a double boiler or heat-proof bowl helps control the temperature. A whisk is essential for emulsifying the egg yolks and butter. For beurre blanc, you just need a small saucepan and a whisk.
Are there any dietary restriction-friendly options?
Unfortunately, no, as both sauces rely heavily on butter and eggs/dairy for their core texture and flavor. There are no suitable vegan or dairy-free alternatives that replicate the authentic consistency.
Can red or white wine vinegar be used in beurre blanc?
White wine vinegar is traditional, but red wine vinegar or even lemon juice can be substituted if needed for the acidic component in beurre blanc. Just adjust the seasoning accordingly.
Does the type of white wine matter for beurre blanc?
Use a crisp, dry white wine without oaky flavors. Sauvignon blanc or unoaked chardonnay are good options. Avoid anything too sweet or with strong residual flavors.
Final Words
In the end, beurre blanc and hollandaise represent two distinct yet equally revered expressions of French butter sauce mastery.
Beurre blanc is an understated, elegant emulsion—deceptively simple yet nuanced with bright acidity to complement delicate ingredients. Hollandaise reigns as the rich, decadent queen, an indulgent celebration of egg yolks and butter coaxed into luscious, velvety thickness through careful technique.
While different in method and texture, both sauces showcase the transformative magic that occurs when humble fats and liquids join in perfect emulsified harmony. From napping seafood to blanketing benedicts, these iconic French butter sauces have earned their place in the saucier’s revered repertoire.
