Plain and Very Crisp Biscuits

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Combine flour, egg yolk, and enough milk to form a stiff paste.

  2. Beat the mixture well and knead until smooth.

  3. Roll the dough very thin and cut into biscuit shapes.

Bake

  1. Bake in a slow oven at 300°F (150°C) until dry and crisp.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

All-purpose flour
Provides the starch and gluten network that forms the structure of the biscuits.
Egg yolk
Adds fat and richness, and helps bind the dough together.
Milk
Hydrates the flour so the mixture can form a workable paste and dough.

The step that matters

Roll the dough very thin. Thin dough has little moisture to drive off, so it dries and crisps in a slow oven. Thick pieces stay soft in the centre and may not turn crisp by the end of baking.

“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.
