Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Asparagus Sauce
Ingredients
Directions
Wash and drain the asparagus tops, cutting them into half-inch lengths.
Boil the asparagus in plenty of salted water for about 15 minutes until tender.
Drain the asparagus in a strainer.
In a saucepan, mix the drained asparagus with thickened veal gravy and the egg yolks, seasoning with salt and cayenne.
Alternatively, mix the asparagus with melted butter and a squeeze of lemon juice before serving.
