Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young peas
- Form the main body of the dish and give it its tender, sweet flavour.
- Lettuce
- Adds moisture and softens into the peas as they stew.
- Flour
- Mixed with butter and stirred in, it thickens the cooking liquid into a light sauce.
- Butter
- Adds richness and a smooth mouthfeel to the stewed peas.
The step that matters
Stirring in the flour and butter. Adding the flour-butter mixture to the hot peas and stirring briefly lets the starch thicken the liquid evenly. Too little stirring leaves lumps, while overcooking can make the sauce pasty.
Swap the peas
How well each one fits the dish's main ingredients (butter, cabbage, lettuce, chive, parsley, sugar, pepper):
