Hollandaise and Mayonnaise

Updated 11-Feb-2021

Both Hollandaise and Mayonnaise are oil-in-water emulsions based on an egg yolk. Making both of them requires raw egg yolk and the addition of mustard, and then the slow adding of oil or butter. Mayonnaise is cold and Hollandaise is hot. Mayonnaise is Spanish and French, and naturally both countries have an excellent source of olives and olive oil. Hollandaise, aka Dutch Sauce, is based on butter from the fantastic Frisian and related breeds of dairy cow.
