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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a bowl, cream together the sugar and butter.
Add the eggs and mix well.
Stir in the baking powder and flour until a dough forms.
Shape and bake
Roll the dough very thin and cut into desired shapes.
Place on a baking sheet and bake until golden.

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, crisp texture.
- Eggs
- Bind the dough and add structure and moisture.
- Baking powder
- Releases gas in the dough, helping the crackers lift slightly and stay light.
- Flour
- Forms the main structure of the dough once it is mixed in.
- Sugar
- Adds sweetness and helps the crackers brown as they bake.
The step that matters
Roll the dough very thin. Thin dough dries and crisps evenly in the oven. Thick pieces stay soft in the middle and may not bake through before the edges over-brown.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
