Gentleman's 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. Beat the egg whites and yolks separately.

  2. Cream together the butter and sugar.

  3. Add the water, flour, baking powder, and salt to the creamed mixture.

  4. Fold in the beaten egg whites gently.

  5. Pour the batter into a greased cake pan and bake at 350°F (175°C) until golden.

Make the jelly

  1. For the jelly, combine 1 egg, 1 cup sugar, grated apples, and lemon juice in a saucepan.

  2. Stir the mixture over heat until it boils, then cool before spreading on the cake.

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

What each ingredient does

Eggs
Whites trapped with air give the cake its light, risen structure, and yolks add richness.
Butter
Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
Flour
Its proteins set during baking to form the cake's structure.
Baking powder
Releases gas during baking so the cake rises.
Sugar
Sweetens the cake and helps create a tender texture when creamed with butter.
Grated apples
Their pectin helps the jelly thicken and set when cooked.

The step that matters

Stir the jelly until it boils. The jelly must reach a full boil so the pectin and sugar can thicken it properly; cooling before spreading lets it set to a spreadable consistency.

Swap the apple
