Why it works: Onion and pepper 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 ↓
Sheep's Head Hash
Ingredients
Directions
Prepare the meat
Clean the sheep's head like a calf's head.
Place it in a pot with the liver and heart, and add the onion.
Simmer gently for 1.5 hours.
Remove the meat and let it cool.
Once cold, chop the meat, heart, and liver finely.
Make the hash and serve
In a stewpan, combine the chopped meat with butter, water or cooking liquid, salt, and pepper.
Heat through and serve with squares of toast around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's head
- Provides the main meat, which becomes tender during slow simmering.
- Liver
- Adds a rich, deep flavour to the meat mixture.
- Heart
- Adds dense, meaty texture and savoury depth to the hash.
- Butter
- Adds fat and richness, helping the chopped meat taste moist and savoury.
The step that matters
Simmer gently for 1.5 hours. A gentle simmer keeps the meat tender and moist. A hard boil toughens muscle proteins and can make the meat dry and stringy.
