Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweet Souffle
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
In a saucepan, heat the milk and gradually add flour to create a thick paste, stirring constantly.
Remove from heat and mix in the egg yolks, salt, and sugar to taste.
Fold and bake
In a separate bowl, beat the egg whites until frothy, then gently fold them into the mixture.
Pour the mixture into a baking dish and bake in a 400°F (200°C) oven for 15 minutes.
Glaze the top with white sugar before serving.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the flour thickens into a smooth paste.
- Flour
- Thickens the milk into a paste that gives the soufflé its body and structure.
- Egg yolks
- Add richness and help set the custard base once baked.
- Egg whites
- Whipped to foam and folded in, they trap air so the soufflé rises and becomes light.
The step that matters
Folding in the egg whites. Egg whites must be beaten until frothy and folded in gently. Stirring or deflating them knocks out the trapped air, so the soufflé will rise less and bake up dense.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (milk, flour, egg, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against milk, flour, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
