Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Beef Steak 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 meat
Preheat the oven to 400°F (200°C).
In a bowl, mix 1 tablespoon of flour, 1 teaspoon of salt, and ½ teaspoon of pepper.
Dip the steak slices in the seasoning mixture.
Layer the seasoned steak in a pie dish.
Skin and slice the mutton kidneys, removing the fat, and dip them in the seasoning.
Continue layering the meat until the dish is full, piling it high in the center.
Add some water to the dish for gravy.
Make the crust
In a separate bowl, mix ½ lb of flour with ½ teaspoon of baking powder.
Cut the butter into the flour until it resembles coarse crumbs.
Add the beaten egg and enough water to form a dough.
Roll out the dough and cover the pie, sealing the edges.
Bake
Bake in the preheated oven for about 45 minutes or until golden brown.

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
- Steak
- Forms the main filling, providing the savoury meat that the pie is built around.
- Mutton kidneys
- Adds a rich, deeper meaty flavour to the filling.
- Flour
- Thickens the seasoning coating on the meat and gives structure to the crust dough.
- Butter
- Cut into the flour to create a short, flaky texture in the crust.
- Egg
- Binds the crust dough and helps it brown in the oven.
- Baking powder
- Gives the crust dough lift so it rises and turns lighter in the oven.
The step that matters
Sealing the crust edges. If the edges are not sealed well, steam and juices escape during baking and the crust can open or go soggy. A tight seal traps heat and moisture so the filling cooks through and the top sets properly.
