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 ↓
French Crackers
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter until light and fluffy.
Add the flour gradually, mixing until well combined.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the mixture.
Shape and bake
Drop spoonfuls of the batter onto a baking sheet.
Brush the tops with egg white and dip in sugar.
Bake for 15-20 minutes or until golden.

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
- Butter
- Creams with the sugar to add richness and a tender, short texture.
- Flour
- Provides the structure that holds the crackers together as they bake.
- Eggs
- Whites are whipped and folded in to lighten the batter; whites brushed on tops help the sugar coating brown.
- Sugar
- Sweetens the crackers and helps the tops brown and crisp in the oven.
The step that matters
Folding in the egg whites. Whites beaten to stiff peaks trap air that lifts the batter. Folding gently keeps that air in; vigorous stirring deflates it and leaves the crackers dense.
