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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Prepare the steak and kidney as for Steak and Kidney Pudding, then dip each piece in flour.
Fill a pie dish with the meat, raising it slightly higher in the center than at the sides, and season with salt and pepper.
Half fill the dish with water.
Make and cover the pastry
For the paste, break the butter into small pieces among the flour, mix in the salt, and add cold water to form a firm paste.
Roll out the paste four times.
Put a border of paste around the wet edge of the pie dish, moisten it, and lay the cover over loosely to allow for shrinkage.
Cut the paste even with the edge of the dish all around.
Brush the top with egg, decorate with paste leaves, and make a vent in the center.
Bake
Bake in a hot oven at 400°F (200°C) for one hour.

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
- Flour
- Coats the meat and forms the structure of the pastry when mixed with fat and water.
- Butter
- Rubbed into flour, it keeps the pastry short and tender and adds richness.
- Steak
- Provides the main meat, which becomes tender through slow cooking in the filling.
- Kidney
- Adds a rich, savoury, deeply meaty flavour to the filling.
- Egg (in the method)
- Brushed on top, it promotes browning and a glossy golden crust.
The step that matters
Adding the cold water to the paste. Cold water keeps the butter in small solid pieces, which create flaky layers; warm water melts the fat and makes the pastry tough. Rolling the paste several times builds further layers and structure.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
