Final answer:
True, Hollandaise sauce is indeed made with whole butter, specifically by using the clarified part of the butter in an emulsion with egg yolks.
Step-by-step explanation:
The question: True/false Hollandaise sauce is made with whole butter is true. Hollandaise sauce is a French sauce, and one of the five mother sauces in French cuisine. It is made by emulsifying clarified butter into egg yolks, along with a bit of lemon juice, salt, and sometimes a little water or white wine. Clarified butter is butter that has been melted so that the milk solids and water are separated from the butterfat. Hence, while whole butter is the basis, the sauce specifically uses the clarified part of the butter.
