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 ↓
Crowdie or Scotch Broth
Ingredients
Directions
Prepare
Remove all fat from the meat broth and pour it into a saucepan.
Place the saucepan on the stove and bring to a boil.
In a bowl, mix the oatmeal with about ½ cup of the broth to form a smooth paste.
Peel and finely chop the onions.
Stir the chopped onions into the oatmeal paste and season with salt and pepper.
Cook and serve
Once the broth is boiling, gradually stir in the oatmeal mixture.
Let it boil for 20 minutes, stirring occasionally to prevent lumps.
Serve in a soup tureen or basin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Thickens the broth as its starch swells during boiling, giving the soup body.
- Meat broth
- Forms the liquid base that carries the flavour of the whole soup.
- Onions
- Add sweetness and aroma as they soften and release their flavour into the broth.
The step that matters
Gradually stirring the oatmeal into the boiling broth. Oatmeal starch clumps when it hits hot liquid unevenly. Pre-mixing it into a smooth paste and adding it slowly while stirring disperses the starch so it thickens evenly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (meat, pepper):
- Capsicumfits better
- Mustardfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against meat, pepper. Candidates are from the same food group and used in at least 100 recipes.
