Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the light, starchy body that the soufflé mixture is built on.
- Egg whites
- Trap air when beaten to stiff peaks, giving the soufflé its rise and airy structure.
- Cream
- Adds moisture and richness, keeping the mash soft and smooth.
- Butter
- Adds fat for richness and a silky mouthfeel in the mash.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
The step that matters
Gently fold the beaten egg whites into the potato mixture. Egg white foam holds the air that makes the soufflé rise. Stirring vigorously knocks out that air, so the bake comes out dense and flat instead of light.
