Why it works: Milk and butter 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 ↓
Potato Pancakes
Ingredients
Directions
Make the batter
Mix the cold mashed potatoes, sweet milk, eggs, and salt thoroughly.
Sift the flour and baking powder together, then add to the potato mixture and beat well.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure so the pancakes hold together when fried.
- Baking powder
- Releases gas in the batter so the pancakes rise and turn light rather than dense.
- Flour
- Provides the starch and gluten network that gives the pancakes body and structure.
- Mashed potatoes
- Supply moisture and starch, giving the pancakes a soft, tender interior.
- Sweet milk
- Adds moisture and loosens the batter to a spoonable consistency.
The step that matters
Fry until golden brown on both sides. The batter is moist and starchy, so the griddle must be hot enough to brown the surface quickly. Browning from the Maillard reaction adds flavour and a crisp exterior, while a cool pan lets the pancakes soak up butter and turn greasy and pale.
