Lemon Jelly Cake

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 cake

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

  2. In a bowl, cream together 1 cup sugar, 1 egg, and 1 egg-sized piece of butter until smooth.

  3. Add 1 cup milk and 3 cups flour, mixing until well combined.

  4. Pour the batter into a greased cake pan and bake until golden.

Make the jelly

  1. For the jelly, combine the juice and zest of 1 lemon, 1 egg, 1 cup sugar, 3 teaspoons corn starch, and 1 cup hot water in a saucepan.

  2. Mix well and bring to a boil, stirring constantly until thickened.

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

What each ingredient does

Flour
Provides the main structure that sets the cake crumb as it bakes.
Eggs
Add structure and richness, binding the batter and helping it set.
Sugar
Sweetens the cake and the jelly and helps the jelly thicken with starch.
Corn starch
Thickens the lemon mixture into a jelly as it heats with the liquid.
Butter
Adds fat for tenderness and flavour in the cake batter.
Lemon juice and zest
Provides acidity and aroma that flavour the jelly.

The step that matters

Stirring the jelly until thickened. Corn starch thickens only when heated to a boil while being stirred. Stopping early leaves the jelly runny, and stirring stops lumps from forming on the bottom of the pan.
