Why it works: Potato and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

The flavor team
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.

Shared aroma: (e)-2-octenal (fatty, green).
Flour and egg barely smell alike, yet cooks put them together in 106,462 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 and starch that give the pancakes their body.
- Eggs
- Bind the grated potato together so the pancakes hold their shape.
- Flour
- Absorbs moisture from the potato and helps the mixture hold together while frying.
- Lard
- Conducts heat to the mixture and promotes golden browning and crisp edges.
The step that matters
Frying in hot lard. Grated potato holds a lot of water and starch. Hot fat sears the surface quickly, forming a crust and driving the browning reaction. If the lard is not hot enough, the pancakes absorb excess fat and turn greasy and soggy inside.
Swap the potato
How well each one fits the dish's main ingredients (flour, egg):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against flour, egg. Candidates are from the same food group and used in at least 100 recipes.
