Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Calf's Foot Broth
Ingredients
Directions
Make the broth
Boil the calf's feet in 2 quarts of water with the onion, carrot, salt, and mace.
Let it boil for 2 to 3 hours, reducing the liquid to 1 quart. If the water evaporates too much, add more water.
Once done, strain the broth and remove the fat.
Finish and serve
Add 1 cup of good wine before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's feet
- Release gelatin into the water, giving the broth body and a silky, setting texture.
- Water
- Acts as the cooking liquid that extracts flavor and gelatin from the calf's feet.
- Wine
- Adds acidity and aromatic depth to the finished broth.
The step that matters
Reducing the liquid by simmering. Long, gentle boiling concentrates the broth and extracts gelatin from the bones and connective tissue. Letting it boil too hard or running dry can make it cloudy, bitter or over-reduced, so topping up water as it evaporates keeps the flavor balanced.
Swap the mace
How well each one fits the dish's main ingredients (onion, carrot, wine):
- Thymefits better
- Garlicfits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against onion, carrot, wine. Candidates are from the same food group and used in at least 100 recipes.
