Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.

Butter and flour 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
- Provide the starch and bulk that form the body of the cake.
- Butter
- Adds fat and richness, contributing flavor and some browning.
- Flour
- Dries the grated potato surface so the cakes brown and hold together better.
The step that matters
Drop spoonfuls into hot drippings and fry until light brown. Hot fat sears the outside quickly, creating a crisp browned crust and limiting oil absorption. If the fat is not hot enough, the cakes soak up grease, turn soggy, and may fall apart.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Potatothe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
