Why it works: Milk and butter match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 81,222 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard base
Boil the milk and cream together.
Melt the butter with salt in a pan.
Mix in the flour and stir for 5 minutes.
Gradually pour in the milk and cream, stirring until smooth and cooked.
Remove from heat and add the grated cheese, pepper, nutmeg, and powdered sugar.
Mix in the egg yolks and beaten egg whites until well combined.
The batter should be thick like cream.
Bake and serve
Prepare small paper trays and fill them ¾ full with the batter.
Bake in a slow oven at 300°F (150°C) for 18 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites set the batter into a light, custard-like texture when baked.
- Flour
- Flour cooked in butter thickens the milk and cream into a smooth sauce.
- Grated cheese
- Cheese adds rich flavor and fat, and helps the custard hold its body.
- Milk and cream
- Milk and cream form the liquid base, adding moisture and richness to the custard.
- Butter
- Butter adds fat and flavor to the roux that starts the sauce.
The step that matters
Gradually pour in the milk and cream, stirring until smooth and cooked. Adding liquid too fast to the flour and butter can form lumps. Stirring constantly while the sauce cooks lets the starch swell evenly, giving a smooth, thick base for the custard.

Fit is the average pairing score against milk, cream, butter, flour, cheese, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
