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
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
Preheat the oven to 400°F (200°C).
Rub the pieces of meat in the flour, then place them in a cooking vessel.
Add the chopped onions and enough stock to barely cover the meat.
Stir well and level the surface.
Stew and bake
Cover the bottom of the cooking vessel with stock and add the meat and onions.
Allow to stew for 1 hour.
Remove the dish and pour the batter over the meat to cover it.
Return it to the hottest part of the oven and bake until nicely browned.
Once browned, lower the heat and simmer gently until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Provides the savoury base of the dish, releasing juices and flavour as it stews and cooks.
- All-purpose flour
- Coats the meat and thickens the cooking liquid, while also forming the batter that sets and browns.
- Milk
- Moistens the batter so it cooks into a tender, set crust rather than a dry one.
- Egg powder
- Adds structure to the batter, helping it set as it bakes.
- Onions
- Add sweetness and aroma as they soften and mingle with the meat juices.
The step that matters
Return to the hottest part of the oven for browning. The batter must be in a very hot oven to rise and brown well before the meat overcooks. Starting the batter in a cooler oven can make it heavy and pale.
Swap the onion
How well each one fits the dish's main ingredients (meat, flour, egg, milk, pepper):
- Capsicumfits better

- Potatofits better
- Onionthe original
Fit is the average pairing score against meat, flour, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
