Why it works: Parsley and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ingredients
Directions
Prepare
Trim and wash the knuckle of veal thoroughly.
Place the veal in a pot and cover it with water.
Cook

Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Provides the main meat, which becomes tender and moist as the collagen slowly breaks down during simmering.
- Butter
- Adds richness and a smooth, fatty finish to the warm meat.
The step that matters
Simmer gently until tender. A gentle simmer lets the tough connective tissue in the knuckle break down into gelatin slowly. A hard boil toughens and dries the outer meat, so keep the water at a quiet simmer for the full cooking time.
Swap the parsley
How well each one fits the dish's main ingredients (veal, butter):
- Sagefits about as well
- Parsleythe original
- Capersfits about as well
- Nutmegfits less well
Fit is the average pairing score against veal, butter. Candidates are from the same food group and used in at least 100 recipes.
