As a follow up to the "which oil?" thread - which kind of morphed into a mayonnaise thread - I thought I might bring up the subject of Hollandaise sauce. I love Hollandaise sauce, and have been making it since I was a teen (when my mother more or less turned over the cooking to me). I love the taste, but I also love the history (of this, and of other foods) Hollandaise sauce was a product of Protestant French refugees (Huguenots) fleeing from (Catholic) France. Mayonnaise was a product of southern France/northern Spain, made of egg yolks and olive oil (and a few other things). Hollandaise was a product of French women, who had fled to Holland, searching for a substitute for their mayonnaise. Holland has no olives, but is famous for its dairy products. It is also, generally, cooler than the Mediterranean coast. So mayonnaise (a cold sauce made with olive oil) morphed into Hollandaise ( a warm sauce made with butter). It is excellent with vegetables (we had some with cauliflower this evening), and, of course, as a part of eggs benedict.
This sauce I have no problem making in the blender, though, for purists, it might be better made with a whisk.. It goes faster, and works perfectly. 3 egg yolks in the blender with a pinch of salt and another of cayenne pepper. Add a tablespoon full of lemon juice. Blend for a moment to mix. Melt 1 stick of butter till just bubbly. While the blender is going (slowly) pour the butter in, as slowly as possible. Scrape the sauce out of the blender with a spatula, and keep warm. Best way is to but the jug that the sauce is in into a pan of warm water. Don't let it get too hot or the eggs will curdle. Leftovers can be kept in the fridge, and reheated gently in or over hot water. There are several off shoots of this sauce; one of my favorites is Bearnaise sauce, which is essentially the same but made with vinegar (rather than lemon juice) and tarragon.
