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 ↓
Mince Served with Mashed Potatoes
Ingredients
Directions
Prepare the potatoes
Wash and scrub the potatoes well in cold water.
Peel the potatoes and remove any eyes or black specks.
Place the potatoes in a saucepan and cover with cold water, adding 1 teaspoon of salt.
Boil and drain
Boil the potatoes for 20 to 30 minutes until tender, checking tenderness with a fork.
Drain the water and let the potatoes steam with the lid half on.
Mash and season
In a small saucepan, heat 1 oz of butter and 1 tablespoon of milk until boiling.
Mash the potatoes smoothly with a spoon or fork, or pass them through a wire sieve for a lump-free texture.
Pour the boiling milk into the mashed potatoes and stir until smooth.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starch that gives the mash its soft, fluffy body once cooked and mashed.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel to the mash.
- Milk
- Adds moisture and creaminess, loosening the mash and making it smooth.
- Mushroom ketchup
- Adds savoury, umami depth to the mash.
The step that matters
Mashing the potatoes with the hot milk and butter. Overworking cooked potato releases starch and makes the mash gluey, so mash gently and stop once smooth. Adding the milk and butter hot keeps the mash warm and lets it absorb the liquid evenly, avoiding lumps.
Swap the potato
How well each one fits the dish's main ingredients (meat, butter, milk, mushroom, ketchup, pepper):
- Capsicumfits better
- Potatothe original
- Shallotfits about as well
- Tomatofits about as well
Fit is the average pairing score against meat, butter, milk, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
