Why it works: Potato and tomato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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
- Potatoes
- Starch that gives the pancakes their bulk and crisp, golden texture when fried.
- Eggs
- Bind the grated potato together and help hold the pancake's shape while it cooks.
- Flour
- Absorbs moisture and helps the grated potato hold together in the pan.
- Butter
- Fat for frying that promotes browning and adds richness to the crust.
The step that matters
Drain the grated potatoes well. Excess water dilutes the batter and turns to steam in the pan, which keeps the pancakes soft and pale instead of crisp and browned. Removing it lets the surface fry and brown properly.
Swap the tomato
How well each one fits the dish's main ingredients (potato, flour, egg, butter):
- Chivefits better
- Leekfits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against potato, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
