Plain Crisp Biscuit

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.

Prepare the dough

  1. Beat the eggs in a bowl.

  2. Mix the eggs with the flour, butter, and salt.

  3. Pour in enough milk to form a stiff dough.

  4. Knead the dough until smooth.

Shape and bake

  1. Roll the dough very thin.

  2. Cut it into round cakes and prick them with a fork.

  3. Bake in a slow oven at 300°F (150°C) until very 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

Flour
Forms the structure of the dough once mixed with liquid and kneaded.
Eggs
Add structure and richness, helping bind the dough.
Butter
Adds fat, which tenderises the dough and contributes to its texture.
Milk
Hydrates the flour so the dough holds together as a stiff dough.

The step that matters

Roll the dough very thin. Thin dough has little moisture and dries out in the oven, so it bakes crisp rather than soft. Thick pieces stay doughy in the centre and will not crisp evenly.

“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.
