Lady Baltimore 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 batter
Cream the butter, then gradually add the sugar.
Mix and sift the flour and baking powder, then add alternately with the milk to the butter mixture.
Fold in the beaten egg whites and almond extract.
Bake in two deep layer cake pans at 350°F (175°C) until golden.
Make the filling and frosting
For the filling and frosting, mix 4 cups sugar and ½ teaspoon cream of tartar with 1 cup cold water.
Bring to a boil and cook until it drops from a wooden spoon like honey.
Add 1 cup of syrup to the beaten whites of 4 eggs.
Return the remaining syrup to the heat and cook until it spins a thread.
Remove from heat and pour over the egg mixture, beating constantly.
As it thickens, add the walnuts, raisins, and vanilla.
Assemble
Spread the mixture between the layers and over the top and sides of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Flour
- Provides the structure that holds the cake's rise and shape.
- Baking powder
- Releases gas in the batter, making the cake rise and lighten.
- Egg whites
- Beaten to foam, they add lift and a light, airy texture.
- Sugar
- Sweetens the cake and helps brown the crust and set the frosting.
- Walnuts
- Add crunch and nutty flavor to the filling and frosting.
The step that matters
Cook the syrup to the thread stage before pouring it over the whites. Sugar syrup must reach the right concentration to set the frosting. Pouring it in at the wrong stage can leave it runny or grainy. Beat constantly so the whites cook evenly and stay smooth instead of scrambling.
