Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Make the stock
Scald the cow heel and place it in a pot with water.
Add chopped carrots, turnips, and onions stuck with cloves.
Simmer for 3-4 hours.
Remove the feet, let them cool, and take off the meat.
Return the bones and any cleaned fish or poultry debris to the pot.
Finish the soup
Make a roux with butter and flour, then strain and mix in the stock gradually.
Add lemon juice and wine to taste, then let it simmer until ready.
Serve with farce‑balls and eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cow heel
- Gives the stock body and a rich, gelatinous texture as it simmers.
- Butter
- Fat that combines with flour to form a roux, thickening the soup.
- Flour
- Starch that thickens the stock when cooked with butter into a roux.
- Wine
- Adds acidity and aroma to balance the rich stock.
- Lemons
- Juice adds sharp acidity that brightens the soup.
The step that matters
Mixing the roux into the stock. Adding stock to the roux gradually, while stirring, keeps the flour smooth and lump-free, so the soup thickens evenly instead of clumping.
