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 ↓
Stewed Ox-tail
Ingredients
Directions
Prepare the tail
Wipe and joint the ox tail, removing any excess fat, then blanch it to cleanse.
Simmer
Place the pieces of tail into a stewpan with the stock and salt; bring to a boil and skim.
Add the vegetables, mace, and peppercorns; simmer for 2.5 to 3 hours.
Thicken and serve
To thicken the sauce, melt the butter, add the flour, and brown them carefully.
Add the stock from the tail to the butter and flour mixture, stirring until boiling.
Return the pieces of tail to the sauce and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Provides rich meat and gelatin that give the stew body and a silky mouthfeel as it simmers.
- Butter and flour
- Cooked together into a roux, they thicken the stock into a smooth, glossy sauce.
- Onion
- Adds aromatic sweetness and savoury depth to the stock as it simmers.
- Carrot and turnip
- Add natural sweetness and body to the stew while they soften in the liquid.
The step that matters
Browning the butter and flour. The flour must be cooked gently until nutty and smooth; if it is rushed or burnt it tastes bitter, and if it is under-cooked it stays pasty. Stirring steadily keeps lumps from forming when the stock is added.
Swap the mace
How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, flour, ketchup):
- Capersfits better
- Parsleyfits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against onion, carrot, turnip, butter, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
