Why it works: Potato and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 938 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Souffle of Cream of Parmesan
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
In a saucepan, warm the butter over low heat.
Add salt and cayenne pepper to taste.
Stir in the potato flour and corn flour until smooth.
Gradually add the milk, stirring until it boils.
Remove from heat and mix in the grated Parmesan cheese and egg yolks one at a time.
Fold and bake
Beat the egg whites until stiff peaks form, then gently fold into the mixture.
Butter a soufflé dish and pour the mixture into it.
Bake at 400°F (200°C) until puffed and golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and make the soufflé rise and turn light.
- Egg yolks
- Enrich the base and add richness, and help set the custard as it bakes.
- Parmesan cheese
- Adds savoury, salty flavour and a little fat to the base.
- Milk
- Forms the liquid base that the flours thicken into a smooth sauce.
- Butter
- Adds fat and flavour to the roux that starts the base.
- Potato flour and corn flour
- Thicken the milk into a stable base that supports the rising egg foam.
The step that matters
Folding in the egg whites. Whites deflate easily when overmixed or stirred vigorously. Folding gently keeps the trapped air, which lifts the soufflé in the oven.
