Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Steak and Kidney Pie
Ingredients
Directions
Prepare the filling
Dice kidney, steak, and onion.
Almost cover with water and cook until tender.
Season with salt and pepper.
Thicken with gravy mix or flour and water.
If a very brown gravy is required, add a little soy sauce (be careful with salt).
Add a good tablespoon of chopped parsley and mix.
Pour the mixture into a lined pie dish.
Make and shape the pastry
Preheat oven to 390°F (195°C).
For the pastry: sift together flour and salt.
Rub one quarter of the shortening into the flour using the tips of fingers.
Add water and lemon juice and mix into a firm dough.
Knead well and roll out into an oblong.
Spread two thirds of the pastry with a further quarter of the shortening, sprinkle with some flour, and fold into three the unbuttered side first.
Press open ends of pastry together, half-turn the pastry and roll out again.
Spread with shortening as before.
Repeat rolling and spreading until the shortening is all used.
Fold and roll once more without fat to the size and shape required for the pie dish.
Assemble and bake
To allow steam to escape, place a pie chimney in the centre and cover with pastry dough, or cut a design into pastry after covering.
Glaze the top with a little milk.
Bake in the preheated oven until the pastry is brown, about 45 minutes.
Nutrition, whole recipe (rough)
Counts 8 of 10 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Kidney
- Provides a rich, meaty flavour and chewy texture after slow simmering.
- Topside steak
- Becomes tender through simmering and adds meaty body to the filling.
- Flour
- Thickens the cooking liquid into a gravy and builds structure in the pastry.
- Butter or shortening
- Layered into the pastry to create flakiness and a tender, short texture.
The step that matters
Rubbing and laminating the fat into the pastry. Keeping the fat in distinct layers creates steam pockets during baking, which produces flaky pastry. Overworking the dough or letting the fat melt into the flour makes it tough.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, sauce, butter, lemon):
- Shallotfits better
- Arrowrootfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pepper, flour, sauce, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
