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 ↓
Browned Potatoes
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
Prepare and mash the potatoes as for plain mashed potatoes.
Heap the mashed potatoes in an oval form on a buttered baking sheet.
Brown and bake
Smooth the top with a knife, dipping the knife in milk to wet every part.
Place in a 400°F (200°C) oven to brown for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, providing starch that sets into a soft, fluffy body.
- Butter
- Adds fat and flavor, and helps the surface brown in the oven.
- Milk
- Adds moisture to the mash and, brushed on the surface, helps it brown evenly.
The step that matters
Smooth the top with milk-wet knife. Wetting the knife lets the surface spread smoothly without tearing. Milk sugars and proteins on the wet surface then brown in the oven, so every part of the top needs coverage.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
