Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Forms the bulk of the dish and becomes tender during the long gentle stew.
- Sweetbreads
- Provide a soft, delicate texture that contrasts with the stewed meat.
- Eggs
- Thicken the gravy as they set gently when stirred in over heat.
- Brown flour
- Thickens the gravy so it coats the meat.
- Salt pork
- Adds fat and savoury richness to the stew as it renders into the gravy.
The step that matters
Stirring in the beaten eggs. Egg proteins set when heated, so the gravy can curdle or turn grainy if it boils hard after the eggs go in. Keep the heat low and stir steadily.
Swap the peas
How well each one fits the dish's main ingredients (mutton, lamb, egg, pork, onion, pepper, parsley):
- Beansfits better
- Sesamefits about as well
- Chickpeafits about as well
- Peasthe original
Fit is the average pairing score against mutton, lamb, egg, pork, onion, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
