Robert Lee 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.

Prepare the cake

  1. Preheat oven to 350°F (175°C).

  2. Cream butter and sugar together until light and fluffy.

  3. Add eggs one at a time, mixing well after each addition.

  4. Gradually add flour and lemon juice, mixing until smooth.

  5. Pour batter into prepared cake pans and bake until a toothpick comes out clean.

Make the icing and finish

  1. Beat egg whites to stiff peaks, then gradually add sugar.

  2. Mix in rind and juice of orange and lemon.

  3. Let cake cool completely before spreading icing on top.

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

What each ingredient does

Eggs
Add structure and richness, and help the batter bind and rise.
Butter
Adds fat for a tender crumb and rich flavor.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed.
Flour
Provides the main structure that holds the cake together as it bakes.
Lemon juice
Adds acidity and bright flavor to the batter.

The step that matters

Let cake cool completely before spreading icing on top.. Spreading icing on a warm cake makes it melt and slide off, and can leave the cake crumbly and soft. Full cooling lets the crumb firm up so the icing sets in place.

Swap the orange
