French Crackers

Oven, in the book's wordsA fairly hot oven

Ingredients

Directions

The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, mix the flour, sugar, and butter until well combined.

  3. Add the egg whites and mix until stiff.

Shape and bake

  1. Roll the dough thin and prick it with a fork.

  2. Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Forms the main structure of the dough as its proteins and starches set during baking.
Sugar
Adds sweetness and helps the crackers brown as they bake.
Butter
Adds fat that tenderizes the dough and gives it a rich flavor.
Egg whites
Whipped until stiff, they add lightness and help bind the dough.

The step that matters

Roll the dough thin and prick it with a fork. Thin dough bakes through and turns crisp rather than soft or chewy. Pricking lets steam escape so the crackers stay flat instead of puffing unevenly.
