Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. 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 bulk and gelatin that gives the broth its body.
- Ham hock
- Adds savoury depth to the stock as it cooks.
- Onions
- Contribute sweetness and aroma as they cook into the stock.
- Browned flour
- Thickens the soup as its starch swells in the hot liquid.
- Yolks of hard-boiled eggs
- Add richness and a creamy texture to the served soup.
- Wine
- Adds acidity and aroma that brighten the finished soup.
The step that matters
Thicken the soup with browned flour. Flour clumps when it hits hot liquid unless it is well dispersed. Stirring it in thoroughly lets the starch granules swell evenly, giving a smooth, uniformly thickened soup instead of lumps.
Swap the mace
How well each one fits the dish's main ingredients (ham, onion, clove, pepper, flour, egg, meat):
- Nutmegfits better
- Turmericfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against ham, onion, clove, pepper, flour, egg, meat. Candidates are from the same food group and used in at least 100 recipes.
