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
- Eggs
- Bind the mixture so it holds together when cooked and sliced.
- Bread crumbs
- Absorb liquid and add body, keeping the filling moist and tender.
- Fat bacon
- Adds fat and moisture, keeping the cooked filling from drying out.
- Sheep's liver
- Provides the rich, savoury body of the meat filling.
The step that matters
Press the mixture tightly into the mold. Firm packing removes air pockets so the filling sets into a dense, sliceable loaf rather than crumbling or leaving gaps during boiling.
Swap the lemon

Fit is the average pairing score against liver, bread, sherry, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
