Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Mutton Hash
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Dice the leftover mutton and chop the boiled potato.
Cook the hash
In a pan, brown the chopped onion and pepper in butter.
Add the mutton and potato to the pan, season with salt and pepper.
Moisten the mixture with broth, leftover soup, or hot water.
Cover the pan and bake in a 350°F (175°C) oven for 50 minutes.
Serve
Serve the hash on a hot dish, garnished with chopped parsley.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover mutton
- Provides the main protein and meaty flavour of the hash.
- Boiled potato
- Adds body and starch that help bind the hash and soak up moisture.
- Butter
- Carries flavour and helps the onion and pepper brown in the pan.
- Onion
- Browns to add sweetness and savoury depth to the base.
- Broth or leftover soup
- Moistens the mixture so it stays tender while it bakes.
The step that matters
Moisten before covering and baking. Too little liquid lets the hash dry out and stick in the oven, while enough moisture keeps the potato and meat tender as the starch softens during baking.
