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

Chestnuts: Form the bulk of the paste, giving the forcemeat its body and mild, starchy sweetness.
Breadcrumbs: Absorb moisture and help the stuffing hold together rather than turning greasy or loose.
Egg yolks: Bind the mixture together and enrich its texture as it sets.
Butter: Adds fat for richness and a softer, moister texture.
Grated ham: Adds savoury, salty flavour that balances the sweet chestnuts.
