Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Ox Tongue
Ingredients
Directions
Prepare the tongue
Wash the pickled tongue thoroughly and soak it in cold water for 48 hours.
Rub the tongue with saltpetre and a little brown sugar, then season with whole pepper.
Soak the tongue in cold salted water for another 4 days, turning it daily.
Cook and serve
Boil the tongue in water with a little of the brine, onion, carrot, bay leaf, and parsley.
Once cooked, skin the tongue and place it in a deep dish.
Pour the strained cooking liquid over the tongue.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickled ox tongue
- Is the main meat, cured and seasoned so it becomes firm and well flavoured.
- Saltpetre
- Helps keep the meat pink and gives the cured flavour and colour.
- Brown sugar
- Balances the salt and adds a mild sweetness to the cure.
- Whole pepper
- Adds aromatic, spicy flavour that soaks into the meat during curing.
The step that matters
Soaking in cold salted water for 4 days. Soaking is what draws out excess salt and cure from the meat. Turning it daily keeps the brine in even contact so the tongue cures evenly rather than unevenly at the surface.
Swap the onion
How well each one fits the dish's main ingredients (sugar, pepper, carrot, parsley):

Fit is the average pairing score against sugar, pepper, carrot, parsley. Candidates are from the same food group and used in at least 100 recipes.
