Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main body of the dish and, as it stews, becomes tender and rich in flavour.
- Sweetbreads
- Add a soft, creamy texture that contrasts with the firmer strips of mutton.
- Eggs
- Beaten eggs stirred into the hot gravy thicken it and give it a smooth, enriched body.
- Browned flour
- Thickens the gravy so it clings to the meat and peas.
- Green peas
- Add sweetness and a bright, fresh flavour against the rich meat.
The step that matters
Stirring the eggs into the gravy. Egg proteins set with heat, so if the gravy is too hot or stirred too fast the eggs can curdle and turn grainy. Keep the heat low and stir steadily while adding the gravy to the eggs.
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.
