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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potato mixture
Mash the potatoes thoroughly.
Beat in the butter, milk, and two raw eggs until light.
Heat the mixture in a greased frying pan, stirring constantly, until stiff enough to handle.
Shape and bake
Shape into a long roll and brush with the beaten egg.
Sift breadcrumbs over the roll.
Place in a buttered baking pan and brown in a 400°F (200°C) oven.
Serve
Serve with a cup of good drawn butter poured over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the roll and give it a soft, tender body.
- Raw eggs
- Bind the mixture and set it so the roll holds its shape.
- Butter
- Adds richness and flavour and keeps the mixture moist.
- Milk
- Loosens the potato mixture and adds moisture for a smooth texture.
- Breadcrumbs
- Form a crisp coating that browns in the oven.
- Drawn butter
- Adds richness and moisture when poured over the finished roll.
The step that matters
Heating the mixture until stiff. Stirring constantly keeps the eggs and starch from catching or scorching on the pan. The mixture must thicken enough to hold a shape, otherwise the roll will slump or break apart when shaped and baked.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, egg):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
