Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Sheep’s Head Broth
Ingredients
Directions
Prepare
Wash the sheep's head thoroughly and soak it in warm water for 2 hours to remove blood.
Place the head in a saucepan and cover it completely with cold water.
Make the broth
Bring the water to a boil, then add the chopped carrots, turnips, onions, parsley, salt, and pepper.
Mix the Scotch oatmeal with a little stock from the pan until smooth, then stir it into the broth. Keep stirring until the broth boils.
Reduce heat and simmer for 1.5 to 2 hours with the lid tightly fastened.

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 meat and bones that give the broth its body and rich flavour.
- Scotch oatmeal
- Starch that thickens the broth as it heats and gives it a fuller texture.
- Carrots
- Add natural sweetness and aromatic flavour to the broth.
- Turnips
- Add mild, earthy flavour and body as they soften during simmering.
- Onions
- Add savoury depth and aroma to the broth as they cook down.
The step that matters
Stirring the oatmeal into the broth. Oatmeal mixed in as a lump or added without being smoothed first will clump and stay grainy. Stirring until smooth, then keeping the broth moving until it boils, lets the starch disperse and thicken evenly.
