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
Prepare the potatoes
Boil the peeled potatoes in water for 20-25 minutes until fork-tender.
Drain the water and return the potatoes to the stove for 1-2 minutes to let steam escape.
Mash the potatoes with a wire beater, adding salt to taste and butter.
Gradually mix in hot milk until smooth and fluffy.
Transfer the mixture to a heated dish without pressing it down.
Beat in a raw egg to bind the mixture, if desired.
Shape and bake
Shape the mixture into conical heaps.
Place the heaps in a greased pan.
Bake in a very hot oven until browned.
Transfer the baked heaps to a hot platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that mashes into a soft, fluffy body.
- Butter
- Adds fat for richness and a smoother, softer texture.
- Hot milk
- Adds moisture so the mash becomes smooth and fluffy rather than stiff.
- Raw egg
- Binds the mixture so the heaps hold their shape during baking.
The step that matters
Bake in a very hot oven until browned. The heaps need a very hot oven so their surfaces dry and brown through the Maillard reaction, giving flavor and color before the interior dries out.
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.
