Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's heads
- Provide the main meat and gelatinous body of the soup.
- Brains (in the method)
- Beaten smooth with butter and oatmeal, they thicken and enrich the soup's texture.
- Oatmeal
- Absorbs liquid and thickens the brain mixture, giving the soup body.
- Butter
- Adds fat and richness, giving a smoother mouthfeel to the brain mixture.
- Carrots
- Release sweetness and body into the broth during the long simmer.
- Onions
- Build savoury depth and aroma as they soften in the broth.
The step that matters
Skim off scum. Foam and impurities rising early in the boil can cloud the broth and carry off-flavours, so they must be removed before the long simmer.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, celery, sugar, mustard, pepper):
