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 ↓
Sweet or Irish Potato Puffs
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, mix the mashed potatoes with the beaten eggs, sweet butter, and hot milk.
Season the mixture with coarse sea salt, sugar, and nutmeg.
Shape and bake
Form the mixture into balls and place them on a buttered baking sheet.
Brush the tops with the remaining beaten egg.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and starch that give the puffs their soft, tender body.
- Eggs
- Bind the mixture and add structure, helping the puffs hold their shape while baking.
- Sweet butter
- Adds richness and fat, contributing a tender texture and savory flavor.
- Hot milk
- Adds moisture and softens the mash, making it easier to shape and tender when baked.
The step that matters
Brush the tops with the remaining beaten egg.. Egg proteins set and brown in the oven, so an even coat gives the puffs a glossy, golden surface. Patchy brushing leads to uneven colour.
