Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
French Peas and Shrimps in White Sauce
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 white sauce
To make the white sauce, combine flour, salt, and pepper in a bowl.
Melt butter in a saucepan, then add the flour mixture.
Gradually stir in scalded milk and cook until thick.
Assemble and bake
Mix French peas and halved shrimps with white sauce.
Fill ramekins or a pudding dish with the mixture and sprinkle with grated cheese.
Bake at 400°F (200°C) until the cheese is melted and slightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a smooth white sauce as it cooks.
- Butter
- Adds fat and richness, and helps form the base of the white sauce.
- Scalded milk
- Forms the liquid of the sauce, which thickens as it cooks and gives it body.
- Grated cheese
- Melts over the top and browns in the oven, adding flavor and color.
The step that matters
Cook the white sauce until thick. Flour must be cooked long enough in the hot butter and milk to thicken fully and lose its raw taste. Stopping early leaves the sauce thin and pasty, and it may thicken further once baked.
Swap the peas
How well each one fits the dish's main ingredients (shrimp, flour, pepper, butter, milk, cheese):
- Beansfits better
- Almondfits better
- Peanutfits better
- Peasthe original
Fit is the average pairing score against shrimp, flour, pepper, butter, milk, cheese. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
