Why it works: Mutton and beef are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,373 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Beef and flour barely smell alike, yet cooks put them together in 10,677 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton fat
- Forms a solid seal over the fruit, keeping air out of the bottles.
- Beef fat
- Adds to the fat seal, helping it set firm and exclude air.
- Flour
- Mixed with water to make a paste that holds the paper cover in place.
The step that matters
Cover immediately with paper and paste. Fat must be poured over the fruit and the bottles sealed right away so that air cannot reach the fruit. Delay lets air in and allows spoilage to start.
