Why it works: Lemon and pepper 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 ↓

Ingredients
Directions
Sweat the onions and leeks in 3 quarts of water with lemon peel, mace, and black pepper until three-quarters cooked.
Add enough water to cover the meat and boil until the goodness is extracted.
Skim the broth and strain it into a large pan.
The next day, carefully remove the fat and warm the broth over a fire.
Clear the broth with the egg whites and yolks, then add a little color and strain through a tamis cloth.
Boil quickly until reduced to a glaze, being careful not to let it burn.
