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 ↓
Ox Tail Soup
Ingredients
Directions
Prepare the ox tails
Joint or chop the ox tails into 1-inch pieces.
Melt the butter in a large pot and brown the smaller pieces of ox tail.
Remove the browned pieces and set aside.
Make the soup
In another pot, combine the vegetables, bay leaves, and cloves.
Add all ingredients to a large pot with cool water.
Turn on the stove, bring to a boil, and simmer for 1.5 hours.
Remove the small pieces of tail after 1.5 hours.
Cook the remaining large pieces for an additional 30 minutes or until very tender.
Remove the large pieces, separate the meat, and return it to the kettle.
Shut off the stove, remove the vegetables, and add salt, pepper, sherry, and caramel.
Can and process
Divide the small joints among cans, fill with the hot broth, cap, tip, and process.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Provide the meat and collagen that enrich the broth and become tender during long simmering.
- Butter
- Browns the ox tail pieces, adding roasted flavor and richness before simmering.
- Onions
- Add sweetness and aromatic depth to the broth as they cook down.
- Carrots
- Add natural sweetness and body to the broth as they soften.
- Turnips
- Add mild earthy flavor and body to the broth as they soften.
- Sherry wine
- Adds acidity and aromatic complexity to the finished broth.
The step that matters
Simmering the large ox tail pieces until very tender. Collagen in the connective tissue breaks down into gelatin only with long, gentle simmering. Stopping too early leaves the meat tough and the broth thin, while a hard boil can make it cloudy.
Swap the onion
How well each one fits the dish's main ingredients (sherry, wine, butter, carrot, turnip, clove, pepper):
