Waterloo Biscuits

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. Cream the butter in a bowl.

  2. Gradually add the sugar, ground rice, and baking powder, mixing well.

  3. Stir in the beaten eggs and vanilla essence.

  4. Roll out the dough thinly and cut into rounds.

Bake

  1. Place on a well-buttered baking sheet and bake at 400°F (200°C) for 10 minutes.

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

Butter
Adds fat that makes the biscuits rich and gives a short, tender bite.
Sugar
Adds sweetness and helps the biscuits brown lightly in the oven.
Ground rice
Gives a crisp, slightly sandy texture and body to the dough.
Baking powder
Releases gas in the dough to give the biscuits a little lift.
Eggs
Bind the dough and add moisture and structure.

The step that matters

Roll the dough thinly. Thin dough dries and crisps evenly in the oven. Thick rounds stay soft and doughy in the centre, so the biscuits will not turn out crisp.

Swap the vanilla

How well each one fits the dish's main ingredients (butter, sugar, rice, egg):

  1. Vanillathe original
  2. Coconutfits about as well
  3. Lemonfits less well
  4. Raisinfits less well

Fit is the average pairing score against butter, sugar, rice, egg. Candidates are from the same food group and used in at least 100 recipes.
