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 ↓

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 stir in flour until it forms a thick paste. Keep stirring continuously over the stove.
Add the egg yolks, a pinch of salt, and sugar to taste.
Fold and bake
Beat the egg whites until frothy and 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 with white sugar before serving immediately.

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
- Egg whites
- Whipped to foam, they trap air and lift the mixture so it rises and stays light.
- Egg yolks
- Enrich the base and help it set into a custard-like texture as it bakes.
- Flour
- Thickens the hot milk into a paste that gives the base body and holds the air.
- Milk
- Forms the liquid base that the flour thickens and the yolks enrich.
The step that matters
Folding the egg whites. Stir gently with a spatula so the whipped foam keeps its air. Overmixing deflates the whites, and the souffle then bakes flat and dense instead of rising.
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.
