Currant Bread

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

Beat the egg yolk with the sugar.
Add a little flour to bind.
Mix in the salt, milk, flour, currants, and baking powder in the order given.
Let the mixture stand for 30 minutes.

Bake

Bake in a preheated oven at 350°F (175°C) until golden brown.

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 that holds the bread together as it sets.
Baking powder: Releases gas in the batter, helping the bread rise.
Egg: Adds richness and helps bind the batter and set its structure.
Sugar: Adds sweetness and helps the crust brown in the oven.
Milk: Supplies the liquid that hydrates the flour and keeps the crumb moist.
