Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch that cooks soft and mashes into a smooth, thick base.
- Green peas
- Add body, sweetness and bulk to the mash.
- Cooking fat
- Adds richness and carries flavour when the vegetables are fried.
- Onion
- Browning in the fat builds savoury, sweet flavour.
- Green maize
- Adds sweetness and texture to the mixture.
The step that matters
Mashing to a smooth consistency. Mashing while the vegetables are still hot and tender gives a smooth texture. Cold or undercooked vegetables stay lumpy and dense, and too much added fluid makes the mash watery.
