Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Peas in Boxes
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.
Prepare the bread boxes
Preheat the oven to 400°F (200°C).
Cut stale bread into 2-inch cubes and form them into boxes.
Brush the inside and outside of the bread boxes with melted butter.
Brown the bread boxes in the oven.
Make the pea filling and serve
In a saucepan, combine the drained peas with 1 cup of milk.
Thicken the milk with 1 tablespoon of butter and 1 tablespoon of flour, rubbed together.
Stir the mixture gently, adding 1 teaspoon of salt.
Fill the bread boxes with the pea mixture and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Dries and firms up, so the cubes hold their box shape and crisp when baked.
- Melted butter
- Adds fat that promotes browning and a rich flavor on the bread boxes.
- Peas
- Provide the main filling, adding body, mild sweetness and color.
- Milk
- Forms the liquid base that the flour thickens into a creamy sauce.
- Flour
- Its starch thickens the milk as it heats, giving the filling body.
The step that matters
Thickening the milk with butter and flour. Flour must be evenly dispersed in the milk before it heats, because its starch thickens only as it warms. Adding it unevenly or stirring poorly leaves lumps and a thin, uneven filling.
Swap the peas
How well each one fits the dish's main ingredients (bread, butter, milk, flour):
- Almondfits better
- Chestnutfits better
- Cocoafits about as well
- Peasthe original
Fit is the average pairing score against bread, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
