The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk 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 starch and bulk that crisp and brown in the hot grease.
- Eggs
- Bind the grated potatoes together and add richness to the batter.
- Flour
- Absorbs excess moisture from the potatoes so the batter holds its shape.
- Baking powder
- Releases gas that gives the latkes a slightly lighter texture.
- Milk
- Adjusts the batter's thickness and adds moisture so it spreads evenly.
The step that matters
Drain the grated potatoes. Grated potatoes release a lot of water. If it is not drained off, the latkes steam instead of frying, so they turn soggy rather than crisp and golden brown.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, pepper, milk):
- Capsicumfits better
- Asparagusfits about as well
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against egg, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
