Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Beef's Tongue with Green Peas
Ingredients
Directions
Prepare the tongue
Parboil the corned tongue until tender.
Remove the tongue from the water, trim off the root, and peel away the skin.
In a broad saucepan, combine the tongue, soup, minced onion, sugar, parsley, and pepper.
Cook and make the gravy
Cover and cook slowly for 1 hour or until tender.
Strain the gravy, adding a little of the boiling water from the tongue.
Mix in the mustard, lemon juice, and thicken with browned flour.
Bring to a boil and serve in a boat.
Serve
Slice the tongue and place on a hot dish.
Top each slice with a spoonful of boiled green peas, drained and seasoned with butter, salt, and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned tongue
- Provides the main meat, which becomes tender through slow, covered cooking.
- Yesterday's soup
- Adds liquid and savoury flavour to the braising liquid that becomes the gravy.
- Browned flour
- Thickens the strained gravy and adds a toasted, nutty flavour.
- Made mustard
- Adds sharp, pungent flavour that cuts the richness of the gravy.
- Lemon juice
- Adds acidity that brightens the gravy and balances the richness of the meat.
The step that matters
Cook slowly, covered, until tender. Tough connective tissue in tongue breaks down into gelatin only with long, gentle heat. A rapid boil toughens the muscle fibres and can leave the meat stringy, so the pot should only simmer.
Swap the peas
How well each one fits the dish's main ingredients (onion, sugar, parsley, pepper, butter, mustard, lemon):
- Chickpeafits better
- Black-eyed peafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against onion, sugar, parsley, pepper, butter, mustard, lemon. Candidates are from the same food group and used in at least 100 recipes.
