Add a bowl to a pot of 1/3 filled simmering water over low to medium heat to make a double boiler. Make sure the bowl is not touching the water.
Add egg yolks and 2 ounces of white wine to a double boiler over low to medium heat.
Vigorously whisk the mixture until it becomes thick and creamy, which takes about 3 to 5 minutes. It should be foamy.
Remove the bowl from the double boiler and slowly pour in warm clarified butter using a ladle or measuring cup while vigorously whisking it until it becomes thick but still pourable. See the notes below if the sauce is too thick or too thin.
Finish the sauce by stirring or whisking in some lemon juice, cayenne pepper, and sea salt to taste. Serve or keep warm until ready to serve.
Notes
Make-Ahead: You can make this hollandaise sauce up to 90 minutes ahead of time.Hot to Store: This does not particularly store well, but you can cover and keep it in the refrigerator for up to 3 days. This will not freezeHow to Reheat: This is not fool-proof but can work. Add the sauce to a double boiler and whisk in a room-temperature egg yolk and 1 to two tablespoons of hot water to help revive and heat the sauceIf the sauce becomes too thick during or before adding in the clarified butter, whisk in a bit of lemon juice or warm water.When whisking the egg yolks in the double boiler, try to whisk vigorously, or they will scramble. If they start to, you can save the sauce by immediately removing the bowl from the double-boiler.You may use less butter as it may thicken with less than the recipe calls for.
