Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Fritters
Ingredients
Directions
Make the batter
Combine the flour in a bowl.
Beat the egg yolks, then add the cold water and gradually stir into the flour, beating vigorously.
Add the salt and olive oil, then fold in the egg whites beaten to stiff peaks.
Let the batter rest for at least 2 hours, but no longer than 10 hours.
Fry and serve
Heat oil in a kettle to 360°F (182°C).
Spoon the batter into the hot oil and fry until golden brown on one side, then turn to brown the other side.
Remove with a skimmer; avoid using a fork to prevent steam from escaping.

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 structure of the batter that holds the fritter together while frying.
- Eggs
- Egg whites beaten to stiff peaks add lightness and help the fritters puff and stay airy.
- Cold water
- Moisture that thins the batter; cold liquid keeps it light and crisp when it hits hot oil.
- Olive oil
- Adds fat to the batter, contributing tenderness and helping the surface brown.
The step that matters
Heat the oil to 360°F (182°C) before frying. Oil that is too cool lets the batter soak up grease and turn heavy, while the hot oil sets the crust quickly. Keeping the temperature steady gives golden, crisp fritters.
