Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish, giving a soft, starchy texture once mashed.
- Butter
- Adds fat and richness, carrying flavour and softening the mashed potato.
- Cream
- Adds moisture and smoothness, keeping the mashed potato soft and easy to shape.
- Onions
- Add sharp, savoury aroma and flavour to the mashed potato.
- Egg
- Brushed on the surface, it helps the shaped potatoes take on an even golden browning.
The step that matters
Mash the potatoes until perfectly smooth. Any lumps left in the potato stay lumpy after shaping and browning. Thorough mashing, while the potato is hot, gives a smooth, even texture that holds its shape.
