What is Hollandaise sauce, and how can you prepare it at home?

Hollandaise is one of the five foundational French mother sauces, alongside béchamel, velouté, espagnole, and tomato. These classic sauces serve as the base for other sauces, often referred to as daughter sauces, in traditional French cuisine. Despite its name, Hollandaise has no connection to Holland and is purely French. It’s now a favorite on American brunch menus. Known for its indulgent, creamy texture, mastering Hollandaise requires some skill. This warm egg yolk and butter emulsion, typically found in dishes like eggs Benedict, offers a rich yet neutral flavor, making it a versatile foundation for adding other ingredients like fresh herbs, hot sauce, mustard, brown butter, or anything else that complements it. Here's how to make your own Hollandaise.

What is Hollandaise sauce?

Hollandaise is a simple blend of egg yolks, melted butter, and a hint of lemon juice. It’s creamy, served warm, and commonly used over eggs and other proteins. Hollandaise is known for being tricky to prepare and highly sensitive to temperature. But once you master the recipe, it becomes an essential skill in any kitchen. Chef Ed Cotton of Jack & Charlie’s 118 in New York suggests making Hollandaise in a double boiler with a wire whisk to achieve the perfect temperature when emulsifying the ingredients. “If the butter is too hot, the sauce may break. If it’s too cold, the sauce will separate when you pour it over your warm poached eggs,” says Cotton. It’s crucial not to overcook the egg yolks. “As a beginner, expect to make some mistakes, but you’ll learn from them,” Cotton advises. “If the sauce appears too thick as you add butter to the yolks, just adjust the consistency with a little warm water.”

Once you’ve perfected Hollandaise, you’ll unlock new possibilities in your culinary skills. “You’ll be ready to try other variations,” says Cotton. “Bearnaise should be your next sauce to tackle.” But first, master the classic Hollandaise.

Hollandaise Sauce Ingredients

Here’s what you’ll need to create a rich, delicious Hollandaise sauce:

Butter: Butter serves as the fat for emulsifying with the warm egg yolk, making it the star ingredient in Hollandaise. Be sure to use high-quality European butter. Egg Yolks: The yolks add richness to the sauce. Choose farm-fresh yolks, which tend to be richer in color and nutrients. Separate the whites for another recipe. Lemon juice: A dash of acid balances the creaminess, with freshly squeezed lemon juice being ideal (though bottled works too). Some chefs opt for yuzu juice for a more tangy twist. Salt: Using unsalted butter and adding salt to taste lets you control the seasoning of the Hollandaise. Try flavored salts for a creative twist on the classic. Cayenne pepper: A pinch of cayenne adds a mild heat to the sauce, though you can substitute with other types of pepper for a variation.

Hollandaise Sauce Recipe

Now that you understand the ingredients of a classic Hollandaise sauce, here’s the step-by-step guide to making it.

Ingredients

• 3 egg yolks
• 1 tablespoon freshly squeezed lemon juice (if possible)
• ½ cup unsalted butter, melted and kept warm
• Pinch of salt, to taste
• Pinch of cayenne pepper, to taste

Method

1. In a heatproof bowl (preferably stainless steel), whisk together egg yolks and lemon juice, or blend for 5-10 seconds until combined.
2. Set the bowl over a simmering pot of water to create a double boiler, and slowly pour in the melted butter, whisking constantly to emulsify.
3. Once the sauce thickens, remove it from the heat. Adjust the seasoning with salt and cayenne pepper to taste. Serve immediately or keep it in a warm water bath until ready to use.
