Why it works: Butter and milk 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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Assemble
Slice enough raw potatoes to fill a moderate-sized pudding dish.
Cover the bottom of the dish with a thick layer of potatoes.
Season with bits of butter, pepper, and coarse sea salt; dredge with flour.
Repeat layering potatoes and seasonings until the dish is full.
Fill the dish with milk.
Bake and brown
Bake covered in a slow oven at 300°F (150°C) for 3 hours.
Remove the cover and brown the top.

Butter and flour 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
- Raw potatoes
- Form the bulk of the dish and set into tender layers as they cook.
- Butter
- Adds richness and fat that carries flavour through the layers.
- Flour
- Dusted between layers, it thickens the milk into a creamy sauce.
- Milk
- Cooks slowly around the potatoes, forming the moist, creamy sauce.
The step that matters
Baking covered at low heat. Slow, covered baking lets the potatoes cook through gently while the milk thickens, so the dish does not dry out or scorch before the potatoes are tender.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, flour, milk):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against butter, pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
