Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pea Souffle
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the white sauce
Make a white sauce by combining flour, fat, and milk in a saucepan over medium heat until thickened.
Prepare the base
Mash the cooked peas to a pulp.
Beat the egg whites until stiff.
Beat the yolks until well combined.
Mix the pea pulp, seasonings, white sauce, and beaten yolks together.
Gently fold in the beaten egg whites.
Bake
Pour the mixture into a greased baking dish.
Bake at 300°F (150°C) until firm.

Flour and milk 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
- Eggs
- Whites trap air for lift, and yolks enrich and help set the custard-like structure.
- Flour
- Thickens the milk and fat into a white sauce that gives the soufflé body.
- Mashed cooked peas
- Provide the main flavour and moisture of the soufflé.
- Skim milk
- Forms the liquid base of the white sauce, adding moisture and body.
The step that matters
Folding in the beaten egg whites. Egg whites hold air bubbles that make the soufflé rise. Folding gently keeps those bubbles intact, while stirring or deflating them leaves a dense, flat result.
Swap the onion
How well each one fits the dish's main ingredients (flour, egg, milk, pepper, peas):
- Asparagusfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against flour, egg, milk, pepper, peas. Candidates are from the same food group and used in at least 100 recipes.
