Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the hollow shells and the bulk of the soufflé filling.
- Thick cream or condensed milk
- Adds richness and moisture to the potato base.
- Egg yolks
- Enrich the filling and help it set when baked.
- Egg whites
- Whipped to a froth to lighten the mixture and help it rise.
- Butter
- Adds fat for a smooth texture and rich flavour.
The step that matters
Mix in the frothed egg whites off the heat. Folding whites into a hot mixture can deflate the foam and cause them to cook unevenly. Keeping the base off the heat lets the whites stay airy so the filling can rise in the oven.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter, sugar, lemon, egg):
- Asparagusfits better
- Leekfits better
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against cream, butter, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
