Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous flesh and bones that give the soup its body and jelly.
- Browned flour
- Thickens the soup and adds a toasted, roasted flavour.
- Butter
- Adds richness and a smooth mouthfeel to the finished soup.
- Brown sherry
- Adds acidity and a deep, sweet-nutty aroma at the end.
- Lean beef
- Adds meaty flavour and savoury depth to the stock.
- Onions
- Add sweetness and savoury depth as they caramelise when fried.
The step that matters
Remove the fat from the chilled stock. Overnight cooling lets fat rise and set on top. Leaving it in leaves the soup greasy, and skimming it cleanly while the stock is cold gives a clear, well-flavoured broth.
Swap the carrot
