The Five Classical French Mother Sauces: Hollandaise
The term “mother sauce” refers to any one of five basic sauces, which are the starting points for making various secondary sauces. The five mother sauces:
Hollandaise is a mild, slightly lemony sauce that is the perfect accompaniment with many things, including eggs Benedict, seafood, shellfish, poultry, and raw or roasted vegetables.
3 egg yolks, room temperature
14 tablespoons cool, unsalted butter cut into 1/4-inch cubes, divided
1 tablespoon fresh lemon juice
Sea salt or kosher salt
Ground white pepper
Whisk the eggs together vigorously in a sloped saucepan over low heat until it starts to thicken, around 3 minutes. Remove from the heat and whisk in 2 tablespoons of the butter until melted. Whisk in the lemon juice and a pinch of salt. Return to the heat, and whisk in and melt the remaining butter in 2-tablespoon increments. Continue until the butter is gone. Season to taste with salt and pepper.
Many additional sauces can be made from this base such as Béarnaise, which is a Hollandaise finished with a reduction of White Wine and tarragon.
