Oat Wafers

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Mix the dry ingredients in a bowl.

  2. Work in the butter until combined.

  3. Add enough warm water to hold the mixture together.

Shape and bake

  1. Place the dough on a floured board and roll it out as thinly as possible.

  2. Cut into rounds the size of a pudding plate, then cut each round into eight wedge-shaped divisions.

  3. Bake on a buttered sheet in a slow oven (300°F / 150°C) until delicately browned.

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

What each ingredient does

Rolled oats
Provide the main body and a toasty, nutty flavour in the wafer.
Wheat preparation
Adds bulk and structure to the dough, helping it hold its shape when rolled thin.
Flour
Forms the gluten network that binds the dough and gives the baked wafer its crisp structure.
Butter
Adds fat for richness and tenderness, and helps the wafers brown.
Sugar
Adds sweetness and encourages browning during baking.

The step that matters

Roll the dough as thinly as possible. Thin dough dries out and crisps during baking, while thick dough stays soft and doughy in the centre. Uneven thickness causes some wedges to burn while others stay pale.
