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 ↓

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
- Flour
- Forms the batter's structure, setting into a crisp coating when fried.
- Egg white
- Whipped to stiff peaks, it adds lightness and airiness to the batter.
- Boiled potatoes
- Form the soft, moist interior of each fritter.
- Salad oil
- Adds fat that keeps the batter tender and helps it brown.
The step that matters
Folding in the whipped egg white. Stiff egg white holds air bubbles that make the batter light. Folding gently preserves those bubbles; stirring vigorously deflates them and leaves the fritters dense.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, flour, egg):
- Jalapenofits better
- Nutmegfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against potato, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
