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.
Make the mash
Peel and boil the potatoes until tender.
Drain and mash the potatoes until smooth.
Mix in salt, butter, and milk or cream until well combined.
Shape and brown
Mold the mashed potatoes into desired shapes.
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
- Provide the starch and bulk that give mashed potatoes their body.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Milk or cream
- Adds moisture and softens the mash for a smoother texture.
The step that matters
Mash until smooth, then mix in the liquid gently. Overworking cooked potatoes releases excess starch, which can make the mash gummy. Warm, well-drained potatoes absorb butter and milk more evenly, giving a smoother result.
