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

What each ingredient does

Potatoes
Break down into a soft, starchy base that gives the mash its body.
Milk
Adds moisture and richness, keeping the mash smooth and creamy.
Green cabbage
Adds texture and a mild, fresh flavour to the mash.
Leek
Contributes a mild onion-like sweetness and aroma to the mash.
Butter
Adds fat and richness on top of the finished mash.

The step that matters

Bringing the milk to a boil before adding the vegetables. Hot milk keeps the mixture warm so the potatoes cook and blend evenly, and the starch absorbs the liquid smoothly rather than turning gluey or cooling the dish. Boiling the milk first avoids a cold, lumpy mash.

Swap the cabbage
