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 filling
Preheat the oven to 400°F (200°C).
Mix 2 tablespoons of flour, 1 teaspoon of coarse sea salt, and ½ teaspoon of black pepper.
Dip the steak slices in the seasoning and layer them in a pie dish.
Add a layer of kidney slices, seasoned, and repeat until the dish is full.
Pour some water into the dish for gravy and pile the meat high in the center.
Make the crust
In a bowl, mix ½ lb. flour, ¼ lb. butter, and ½ teaspoon baking powder.
Add ½ cup of water and half of the beaten egg to the flour mixture to form a stiff paste.
Roll out the paste to about ¼ inch thick, fold it in thirds, and roll again.
Assemble and bake
Wet the edge of the pie dish and place a narrow band of paste around it.
Cover with the remaining paste, cut to size, notch the edges, and brush with the remaining egg.
Make a large hole in the top and decorate with leaf‑shaped pieces of paste.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the main body of the pie and provides meaty flavor as it cooks.
- Sheep's kidneys
- Adds rich, deep meaty flavor to the filling.
- Flour
- Thickens the juices into gravy and helps the seasoning cling to the meat.
- Butter
- Adds fat that makes the crust tender and flaky as it bakes.
- Baking powder
- Releases gas during baking to lighten the crust.
- Egg
- Brushed on top, it helps the crust brown to a golden color.
The step that matters
Forming the stiff paste and rolling it out. Working the butter into the flour and water without overmixing keeps the crust tender. Folding and rolling builds layers, so the crust bakes flaky instead of dense.
