Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green peas
Form the bulk of the dish and give it its main body and sweet, vegetal flavour.
Cabbage lettuce
Softens as it stews, adding tender leaves and a mild, fresh vegetable flavour.
Gravy
Provides the liquid that cooks the vegetables and carries savoury flavour through the dish.
Butter
Rolled in flour, it melts into the hot liquid and thickens the mixture while adding richness.
Essence of ham
Adds concentrated smoky, savoury ham flavour to the stewed vegetables.

The step that matters

Stirring in the floured butter. Flour-coated butter must be stirred into simmering liquid and kept moving so the starch hydrates evenly. Stopping the stir risks lumps, and boiling too hard can make the thickened mixture separate or turn gluey.
