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 ↓
Mashed Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Peel and boil the potatoes until tender.
Mash the potatoes until smooth.
Mix in salt, butter, and milk or cream until well combined.
Shape and brown
Mold the mashed potatoes into your desired shape.
Brown the molded potatoes in a 400°F (200°C) oven until golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish; mashing them creates a smooth, soft texture.
- Butter
- Adds fat and richness, giving the mash a silky mouthfeel and flavor.
- Milk or cream
- Adds moisture so the mash becomes smooth and spreadable rather than stiff.
The step that matters
Mash the potatoes until smooth. Overworking or undermashing changes the texture. Starch cells rupture as they are mashed, so mashing too long can make the potatoes gluey, while leftover lumps spoil the smooth finish. Warm liquid mixed in well helps the mash stay creamy.
