Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Provides the meat, which becomes tender and rich during the long, slow simmer.
- Flour
- Browned in the fat, it thickens the cooking liquid into a body-rich sauce.
- Fat
- Carries the frying and browning, building deep flavour on the onion and tail pieces.
- Onion
- Fried until golden and strained, it adds sweetness and savoury depth to the sauce.
- Lemon juice
- Added at the end, it contributes acidity that brightens the rich sauce.
The step that matters
Allow the flour mixture to brown. Browning the flour in the fat develops nutty, roasted flavour and colour in the sauce. Pulling it too early leaves a pale, raw-tasting base, while letting it burn gives a bitter taste.
Swap the mace
How well each one fits the dish's main ingredients (onion, clove, pepper, lemon, flour):
- Cardamomfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against onion, clove, pepper, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
