Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Softens into the stew, adding bulk and a mild, tender body as it cooks.
- Green peas
- Provide the main body and sweetness, becoming soft and tender through long simmering.
- Butter
- Adds richness and a smooth mouthfeel, and carries the flavour of the seasonings.
- White wine
- Adds acidity and aroma that brighten the savoury stew.
- Liebig's extract
- Concentrates savoury meaty flavour into the broth.
The step that matters
Simmer until the peas are soft. Peas need sustained gentle simmering to soften fully. Stopping early leaves them firm and floury, while a hard boil can break them apart and toughen the skins.
