Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare the dough

  1. In a bowl, mix the oat meal and flour.

  2. Rub the butter and brown sugar together until well combined.

  3. Add the ground spice, salt, and baking soda to the mixture.

  4. Moisten slightly with a little cold water.

  5. Add more flour as needed to achieve a firm dough.

Cut and bake

  1. Roll out a small piece of dough as thin as possible.

  2. Cut into shapes with a sharp fluted cutter.

  3. Bake in a hot oven at 400°F (200°C) until golden.

    Shared aroma: guaiacol (smoky, sweet).

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

Oat meal
Provides the main body and a crisp, grainy texture to the wafers.
Flour
Builds structure so the dough holds its shape when rolled and cut.
Brown sugar
Adds sweetness and a caramel note, and helps the wafers brown.
Butter
Adds fat that tenderises the dough and gives a rich flavour.
Baking soda
Reacts to lighten the dough and promotes browning in the oven.

The step that matters

Roll out the dough as thin as possible. Thin dough dries out and crisps in the oven, while thicker pieces stay soft and bake unevenly. Keeping the thickness even ensures all the wafers finish at the same time.
