Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 400°F (200°C).
Mix a pinch of salt with the flour.
Beat the flour mixture with the eggs until smooth.
Gradually add the milk, beating until the batter is thick and lump-free.
For best results, prepare the batter 1-2 hours in advance and re-beat before pouring.
Assemble and bake
Grease a baking dish with butter and lay the beef steak and kidneys at the bottom.
Pour the batter over the meat.
Bake for 1½ to 2 hours 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
- Eggs
- Bind the batter and help it set into a firm, sliceable structure as it bakes.
- All-purpose flour
- Forms the starch and gluten network that gives the batter its body and structure.
- Milk
- Hydrates the flour and adds moisture, so the batter bakes up tender and custard-like.
- Beef steak
- Provides the main meat and savory flavor that the batter bakes around.
- Kidneys
- Adds a rich, savory, deeper meaty flavor to the dish.
The step that matters
Beating the batter smooth and lump-free. Flour lumps stay dry and do not hydrate fully, leaving pockets in the batter. Thorough beating hydrates the starch and gluten evenly so the batter rises and sets smoothly around the meat.
