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.

Prepare

Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, and sugar.
Add the beaten eggs and milk, and mix well.
Pour the mixture into a buttered baking tin.

Bake and serve

Bake for 15 minutes.
Serve cold as a cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour: Forms the main structure of the batter as its proteins set during baking.
Baking powder: Releases gas in the batter, helping it rise and become light.
Granulated sugar: Adds sweetness and helps give the crumb a tender texture.
Eggs: Bind the batter and add structure and richness as they set.
Milk: Adds moisture and hydrates the flour to form the batter.
