Why it works: Potato and milk are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Potato Pancakes
Ingredients
Directions
Prepare the batter
Grate the potatoes and strain through cheesecloth.
Measure the potato water and use half that amount of milk.
In a bowl, mix the grated potatoes, milk, salt, beaten egg yolks, and enough flour to create a stiff batter.
Gently fold in the beaten egg whites.
Fry
Heat lard in a pan and fry the batter until browned on both sides.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Raw potatoes
- Provide the starchy bulk that gives the pancakes their body and crisp-edged texture.
- Flour
- Binds the grated potato into a stiff batter that holds its shape in the pan.
- Egg yolks
- Add richness and help bind the batter together.
- Egg whites
- Whipped air folded in gives the batter lightness.
- Milk
- Adds moisture and softness to the batter.
- Lard
- Conducts heat in the pan and promotes browning and a crisp surface.
The step that matters
Gently fold in the beaten egg whites. Beaten egg whites hold air bubbles that lighten the batter. Stirring hard or too long collapses those bubbles, leaving denser pancakes.
Swap the potato
How well each one fits the dish's main ingredients (milk, egg, flour):
- Arrowrootfits better
- Asparagusfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
