Why it works: Flour and butter 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 ↓
Frying Batter for Vegetables
Ingredients
Directions
Make the batter
In an earthen bowl, make a hollow in the center of the flour.
Add melted butter and enough water to create a light batter.
Mix well until smooth, ensuring no lumps remain, and add a little salt.
Let the batter rest for one hour before using.
Finish and use
When ready, beat the egg whites until stiff and gently fold them into the batter.

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
- Flour
- Forms the structure that holds the batter together and coats the food when fried.
- Melted butter
- Adds richness and fat, giving the fried coating tenderness and flavor.
- Egg whites
- Beaten until stiff, they add air and lightness to the batter for a crisp, airy coating.
The step that matters
Folding in the beaten egg whites. Stiffly beaten whites trap air that lightens the batter. Stirring them in vigorously knocks that air out, so the coating fries up heavier. Fold gently, just until combined.
