Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Knuckle of Veal with Rice or Green Peas
Ingredients
Directions
Make the stew
Cover the knuckle of veal with water in a pot.
Bring the water to a slow boil, skimming off any scum.
Add 1 teaspoon of salt and simmer for 30 minutes.
Stir in the washed rice and continue to simmer for 1.5 hours until both the meat and rice are tender.
Season with cayenne and mace 20-30 minutes before serving.
Optional additions
For a richer stew, use veal broth instead of water.
If desired, add green peas after skimming the scum.
Season with white pepper and omit mace if using peas.
Optionally, add sliced cucumbers or shredded lettuces for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Provides meat and gelatin-rich body that turns the stew savory and thick as it simmers.
- Rice
- Absorbs liquid and softens, thickening the stew and giving it body.
The step that matters
Skimming the scum after the water boils. Scum is coagulated protein and impurities that rise as the water heats. Removing it keeps the broth clear and less bitter or greasy.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (veal, rice, pepper, mace, white pepper, cucumber, lettuce):
- Walnutfits about as well
- Beansfits about as well

Fit is the average pairing score against veal, rice, pepper, mace, white pepper, cucumber, lettuce. Candidates are from the same food group and used in at least 100 recipes.
