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 ↓
A Nice Dish From Cold Beef, with Mashed Potatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Mash the potatoes with hot milk, egg yolk, butter, and salt.
Slice the cold beef and place it in a pie dish.
Season the beef with pepper, salt, and add a little beef gravy.
Cover the beef with the mashed potatoes, smoothing it out.
Score the potato crust into squares with a knife.
Bake and serve
Bake in a 350°F (175°C) oven until browned on all sides.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form a soft mashed topping that bakes into a browned crust.
- Egg yolk
- Adds richness and helps the mashed potato set firm and hold its shape.
- Butter
- Adds fat for richer flavour and a softer, smoother mash.
- Cold beef
- Forms the savoury meat filling beneath the potato layer.
- Beef gravy
- Adds moisture and meaty flavour to the beef filling.
The step that matters
Bake until browned on all sides. The potato topping browns through Maillard reactions at the surface, which need enough heat and time. Too little baking leaves it pale and the filling underheated.
Swap the potato
How well each one fits the dish's main ingredients (beef, pepper, milk, egg, butter):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Tomatofits less well
Fit is the average pairing score against beef, pepper, milk, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
