Why it works: Pepper and lemon 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 ↓
Ragout of Mutton
Ingredients
Directions
Prepare the mutton
Place thick slices of boiled mutton in a deep dish, pour claret wine over them, cover, and let sit for 1 hour.
In a pot, boil the bones and refuse portions with 4 cups of cold water until it reduces to 1 pint, strain, let cool, and remove the fat.
Make the gravy
In a saucepan, combine the strained gravy, minced onion, pepper, salt, and tomato ketchup, then boil until it reduces to 1 cup.
Stir in browned flour mixed with cold water and simmer for 3 minutes.
Finish and serve
Add the sliced mutton, wine, grated lemon peel, and currant jelly, then heat slowly without boiling the meat.
Once heated, pour the ragout into a deep dish and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled mutton
- Provides the main meat, which stays tender when heated gently rather than boiled.
- Claret wine
- Adds acidity and aroma while soaking and flavouring the meat.
- Bones and refuse portions of mutton
- Create a rich, gelatin-containing stock that gives the gravy body and depth.
- Browned flour
- Thickens the gravy and adds a toasted, nutty flavour.
- Currant jelly
- Adds sweetness and a fruity note that balances the savoury gravy.
The step that matters
Heat the meat slowly without boiling. Boiling toughens muscle proteins and squeezes out juices, leaving the mutton dry and chewy. Gentle heating keeps it tender and moist.
Swap the onion
How well each one fits the dish's main ingredients (mutton, wine, pepper, tomato, ketchup, flour, lemon):
- Capsicumfits better
- Shallotfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against mutton, wine, pepper, tomato, ketchup, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
