Blender Hollandaise Sauce
Makes 1 cup
Adapted from The Joy of Cooking by Irma S. Rombauer and Marion Rombauer Becker (1964 edition)The sauce must be hot when served; either make it at the very end or keep it warm by putting the blender container in warm (not hot) water. This makes enough for 3 servings of Eggs Benedict or Rockefeller and I usually only make it for 2. I’ve tried making a smaller amount and it doesn’t work; without the full amount of bubbling hot butter, there isn’t enough heat to cook the eggs. Leftover hollandaise makes a terrific sauce for asparagus or other green vegetables. To use leftover hollandaise, slowly reheat the sauce in a water bath.
3 egg yolks
2 Tbsp. lemon juice
Pinch of cayenne pepper
1/4 tsp. salt
1/2 cup butter (1 stick)
Put the egg yolks, lemon juice, cayenne, and salt in a blender. Melt the butter until it is hot and bubbling (this is easiest to do in a microwave). Blend the egg yolks on high for a few seconds, and then pour in a steady stream of hot bubbling butter. The hollandaise should now be done; if it isn’t thick enough, continue to blend for a few more seconds. If the sauce is too thick add a tiny amount of lemon juice or water. Taste and add salt, cayenne, or lemon juice as needed.
