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 ↓
Mock Turtle Soup
Ingredients
Directions
Cook the calf's head in the stock with the herbs, lemon rind, peppercorns, cloves, and ham until tender.
Remove the ham, chop it finely, and cut half the meat from the head into small pieces.
Return the bones to the pan and cook gently for 1 hour longer.
Strain the stock, thicken it with the flour, and add pepper, salt, ketchup, and sherry.
Add the egg balls, forcemeat balls, and pieces of meat, then serve.
