Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Pie
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 the filling
Cut the beef into small, thin pieces, removing excess fat.
If there are any ragged bits or bones, cover them with cold water and boil slowly for an hour to make gravy.
To the stock, add the onion, salt, chili sauce, and beef; simmer for 10 minutes.
Thicken the gravy, let it boil briefly, then cool.
Assemble and bake
Layer the mixture in a 2-quart baking dish with sliced hard-boiled eggs.
Cover with puff pastry, making a steam vent in the center.
Bake at 400°F (200°C) for 30 minutes.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Beef
- Provides the main filling and savory meaty flavor once simmered in the gravy.
- Flour
- Thickens the gravy so it holds together rather than running out of the pie.
- Eggs
- Add richness and firm slices of set egg white and yolk to the layered filling.
- Chili sauce
- Adds sweet-sour tang and warmth to the gravy.
- Puff pastry (in the method)
- Forms a flaky, browned crust that seals the filling in the dish.
The step that matters
Thicken the gravy, then cool it before assembling. Flour needs to be fully cooked in the boiling liquid to thicken properly and lose its raw taste. Cooling the filling before adding pastry keeps the crust from becoming soggy and stops steam from lifting it early.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour, sauce, egg):
- Shallotfits better
- Chivefits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against beef, flour, sauce, egg. Candidates are from the same food group and used in at least 100 recipes.
