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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Pounded chestnuts: Make up the bulk of the forcemeat and give it its main body and flavour.
Egg yolks: Bind the mixture together so it holds its shape when stuffed.
Bread crumbs: Absorb moisture and add body so the stuffing stays soft rather than dense.
Butter: Adds fat for richness and a softer, moister texture.
