Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cold Meat and Potato, Baked
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a frying pan, melt the cold butter over medium heat.
Stir in the chopped onion and flour, mixing constantly until smooth and frothy.
Add the cold milk or water, season with salt and pepper, and bring to a boil.
Stir in the finely chopped cold meat and heat thoroughly.
Assemble and bake
Transfer the mixture to a well-buttered shallow dish.
Spread the mashed potatoes over the top.
Bake in a preheated oven at 350°F (175°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the flour roux and adds richness and flavor to the filling.
- Flour
- Thickens the milk or water into a smooth, binding sauce that holds the meat together.
- Milk or water
- Forms the liquid base that the flour thickens into a creamy sauce.
- Cold meat
- Provides the main filling, bound in the sauce and heated through.
- Mashed potatoes
- Forms the topping that softens and browns in the oven.
The step that matters
Thickening the sauce before adding the meat. Flour must be cooked with the butter and stirred constantly so it becomes smooth and frothy; then the liquid is brought to a boil so the starch thickens fully. Skipping this leaves lumps or a thin, watery sauce.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, meat, potato):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against butter, flour, milk, pepper, meat, potato. Candidates are from the same food group and used in at least 100 recipes.
