Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Beef Steak and Kidney Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Cut the steak into thin strips, 1‑1½ inches wide. Roll them up and dip in a mixture of flour, salt, and pepper.
Place a layer of the steak at the bottom of a pie dish.
Slice the kidney thinly, removing all fat. Season and layer it over the steak.
Continue layering until the dish is full, raising the filling in the center.
Assemble and bake
Half fill the dish with stock. Wet the edges of the dish and cover with strips of pastry.
Moisten the pastry and cover with more pastry. Cut a hole in the center and decorate the top with pastry leaves.
Brush the top with beaten egg. Bake in a 400°F (200°C) oven for 10 minutes, then reduce to 350°F (175°C) and bake for about 1½ hours.
Serve
When cooked, fill the pie with well‑seasoned gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the main meaty filling, becoming tender through long, slow baking.
- Kidney
- Adds a rich, deep meaty flavor to the filling.
- Flour
- Coats the meat and thickens the stock into a gravy-like sauce.
- Short or flaky pastry
- Forms the crisp, rich crust that encloses the filling.
- Egg
- Brushed on top, it promotes even browning and a glossy finish.
The step that matters
Bake at the two-stage temperature. Starting hot sets and browns the pastry quickly, then the lower heat lets the meat tenderize without drying or burning the crust.
