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 ↓
Shad Roe Croquettes
Ingredients
Directions
Cook the roe in boiling salted water, with one tablespoonful of lemon juice, for twenty minutes. Drain, cut in fine pieces, mix with the heavy white sauce that has had one egg added to and cooked in it for five minutes. Season with salt and pepper. When cold, mould, egg and crumb. Serve with Hollandaise or cucumber sauce.
