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 ↓
Steak and Kidney Pie
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.
Prepare the filling
Mix 2 teaspoons of flour with some pepper and salt on a plate.
Dip each piece of steak lightly in the flour.
Roll a piece of kidney and a piece of fat alternately in the slices of meat.
Pile the meat mixture high in a dish and pour in the water or stock.
Assemble the pie
Make a shortcrust pastry as per standard instructions.
Wet the edge of the dish.
Line the wet edge with a strip of pastry.
Cover the dish with pastry.
Trim the edges.
Cut a small hole in the center.
Decorate the top with leaves cut from pastry trimmings.
Brush the top with water.
Bake
Bake in a 350°F (175°C) oven for 1.5 hours.
Once the crust has some color, cover it with a piece of paper rubbed with dripping.

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
- Provides the main meat body and rich savory flavor as it cooks slowly in the filling.
- Kidneys
- Add a deep, earthy meaty flavor and tender texture to the filling.
- Flour
- Lightly coats the steak, helping it brown and thickening the juices into a gravy.
- Dripping
- Adds richness and fat that carries flavor and helps the pastry and paper brown.
- Water or stock
- Provides moisture so the meat cooks gently and forms a gravy under the crust.
The step that matters
Covering the crust with greased paper. Once the crust has colored, a paper cover shields it from over-browning while the filling finishes cooking slowly, so the pastry bakes through without burning.
