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 ↓

Ingredients
Directions
The book says “a moderate 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 butter over medium heat.
Add the diced steak, ham, and chopped onions; simmer for 15 minutes.
Stir in the sliced potatoes, beef stock, salt, pepper, and flour; cook for 20 minutes.
Bake
Pour the mixture into a baking dish lined with pastry.
Cover and bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the meaty body and savory flavor of the filling as it simmers.
- Potatoes
- Add starch that thickens the filling and gives it a hearty texture.
- Flour
- Thickens the stock into a stable sauce that holds the filling together.
- Beef stock
- Supplies moisture and savory depth that cooks the other ingredients.
- Butter
- Adds fat and richness, and helps the onions brown in the pan.
- Onions
- Soften and turn sweet as they cook, adding aroma to the filling.
The step that matters
Cooking the flour into the stock. Flour only thickens the liquid properly when it is heated long enough with the stock. Stirring it in and simmering for the full time lets the starch swell and the raw flour taste cook off, so the filling does not stay thin or floury.
Swap the onion
