Why it works: Onion and pepper 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 ↓

Ingredients
Directions
Prepare
Peel and wash the potatoes, slice them 1/4 inch thick, then dry on a cloth.
Chop the onions finely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes (in the method)
- Form the bulk of the filling and give it a soft, starchy texture.
- Onions
- Add sweetness and aroma when fried until softened and lightly browned.
- Eggs
- Bind the batter and set it as it bakes, giving the pie its structure.
- Milk
- Provides the liquid that combines with the eggs to form a set custard.
- Wheatmeal (in the method)
- Thickens the batter and gives it body so it holds the potatoes and onions.
The step that matters
Fry the potatoes and onions until they begin to brown and soften. Stirring often spreads heat evenly and stops the vegetables from scorching. Potatoes that are not softened before baking stay firm in the set batter, and browning adds flavour through caramelisation.
Swap the onion
