Cornish Currant Cake

Oven, in the book's wordsA moderate oven

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.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Mix the flour, salt, and baking powder in a bowl.

  3. Rub in the butter or lard until well combined.

  4. Add the sugar, currants, lemon peel, and nutmeg.

Make and bake

  1. Beat the eggs with the milk and mix into the dry ingredients to form a stiff mixture.

  2. Place the mixture on a floured baking sheet and roll out to about ½ inch thick.

  3. Make several incisions on top with a knife.

  4. Bake for about 40 minutes.

  5. Brush the top with egg white and sprinkle with sugar.

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 cake as the starches set in the oven.
Butter or lard
Coats the flour particles, giving the cake a tender, short crumb.
Eggs
Bind the mixture and add richness and structure as they set.
Baking powder
Releases gas in the dough, helping the cake rise.
Castor sugar
Adds sweetness and helps the top brown as it bakes.
Milk
Adds moisture that hydrates the flour and brings the dough together.

The step that matters

Rub in the butter or lard until well combined. The fat must be evenly distributed among the flour particles so it coats them. This limits gluten development and keeps the crumb tender rather than tough.

Swap the currant
