Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Steam the sugar with the butter.

  2. Add the beaten egg, coffee, salt, milk, and baking powder.

  3. Sift in the flour and beat thoroughly.

  4. Stir in the floured currants.

Bake and serve

  1. Pour into a well-buttered square pan.

  2. Sprinkle with cinnamon and powdered sugar.

  3. Bake in a 350°F (175°C) oven for 30 minutes.

  4. Cut into small squares when cold.

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
Provides the structure that holds the squares together as they set.
Butter
Adds richness and tenderness to the crumb.
Egg
Binds the batter and adds structure and richness as it sets.
Baking powder
Releases gas during baking so the squares rise and turn light.
Sugar
Sweetens the squares and helps brown the surface as they bake.
