Put two yolks of egg in a stewpan, with half a tablespoonful of flour,
half a clove of garlic well scraped, a small quantity of cayenne pepper,
two ounces of butter, half a teaspoonful of salt, and the juice of half
a lemon; place it over a moderate fire, and stir it until it becomes
rather thick; then take it off the fire, stir in two tablespoonfuls of
oil by degrees, then eight of melted butter; if you should require to
warm it again, stir it in a bain marie of hot water. Use where required.
