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 Patties
Ingredients
Directions
Prepare
Peel and wash the potatoes, then grate them on a coarse grater.
In a bowl, combine the grated potatoes, eggs, yeast (or baking powder), salt, milk, and flour. Mix well.
Fry
Heat lard in a pan until smoking hot.
Drop spoonfuls of the mixture into the hot lard and fry until brown and crisp, like doughnuts.

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
- Potatoes
- Provide the bulk of the patty and moisture that steams inside while the outside fries.
- Eggs
- Bind the grated potato together so the patties hold their shape.
- Quick yeast or baking powder
- Lifts the batter with gas bubbles so the patties are lighter inside.
- Flour
- Adds starch that thickens the batter and helps the patties crisp and brown.
- Milk
- Adds moisture and softness to the batter.
The step that matters
Heating the lard until smoking hot before frying. Hot fat seals the outside of each spoonful quickly, so the patties brown and crisp rather than soaking up grease and turning heavy. Starting with cool fat makes them greasy and dense.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, flour):
- Arrowrootfits better
- Asparagusfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
