Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Grind or crush the oats.

Make and shape the dough

  1. Mix the oats with the fat, milk, baking soda, molasses, and salt.

  2. Roll out the mixture into a thin sheet and cut into squares.

Bake

  1. Bake for 20 minutes in a moderate oven at 350°F (175°C).

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

What each ingredient does

Rolled oats
Form the bulk of the crackers and give them a hearty, crisp-textured base.
Baking soda
Reacts with the molasses to lighten the dough and promote browning in the oven.
Molasses
Adds sweetness, a deep flavor, and some moisture, and contributes to browning.
Fat
Adds richness and tenderness, helping the crackers bake crisp rather than tough.
Milk
Moistens the oats so the mixture binds and can be rolled into a sheet.

The step that matters

Rolling the dough thin. Rolling the mixture into a thin, even sheet matters because thick spots bake more slowly and stay soft, while thin areas can scorch. Even thickness gives a uniformly crisp cracker.
