Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast
- Provides the meat that becomes tender during long, gentle stewing.
- Butter and flour
- Together form a roux that thickens the stock into a gravy.
- Stock
- Cooks the lamb slowly and forms the base of the gravy.
- Green peas
- Add sweetness and color as a side arranged around the meat.
The step that matters
Thickening the gravy just before serving. Flour needs to be cooked in hot liquid long enough to lose its raw taste and thicken properly. Adding it too early or boiling it unevenly can leave lumps or a pasty flavor, so bring the gravy to a full boil once the butter and flour are added.
Swap the peas
How well each one fits the dish's main ingredients (lamb, pepper, butter, flour, mushroom):
- Almondfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against lamb, pepper, butter, flour, mushroom. Candidates are from the same food group and used in at least 100 recipes.
