Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
D Mutton
Ingredients
Directions
Prepare
Cut the mutton into slices about 2 inches square.
Put the mutton into a stewpan.
Skin and slice the onion, then add it to the stewpan.
Make the hash
In a basin, mix the flour with hot water gradually, stirring until smooth.
Pour the mixture over the mutton and simmer gently for 30 minutes.
Finish and serve
Roll up the mutton slices, skewer them, and fry until golden.
Turn the hash onto a hot dish and arrange the bacon rolls around the center.
Serve hot, optionally with fried onions or fried potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Forms the bulk of the dish and gives its main meaty flavour.
- Flour
- Thickens the cooking liquid into a smooth, lightly bound sauce.
- Onion
- Adds savoury sweetness and aroma as it softens in the liquid.
- Bacon
- Adds salty, smoky fat and browning to the rolls served with the hash.
The step that matters
Stirring the flour and hot water until smooth. Adding flour to liquid without stirring it into a smooth paste first lets lumps form, and those lumps do not dissolve well during simmering. Adding the hot water gradually keeps the mixture even, so the sauce thickens evenly.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, flour, sauce):
- Shallotfits better
- Capsicumfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against mutton, pepper, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
