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
Cream the butter and gradually add the sugar.
Mix and sift the flour and baking powder, then add alternately with the milk to the butter mixture.
Add the almond extract and the beaten egg whites.
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 in a saucepan.
Bring to a boil and cook until the mixture drops from a wooden spoon like honey.
Add 1 cup of this syrup to the beaten egg whites and beat constantly.
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 until thickened.
Fold in the walnut pieces, raisins, and vanilla.
Assemble
Spread the filling 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
- Creams with the sugar to give the cake a tender, rich crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Egg whites
- Beaten to foam, they lighten the batter and set the frosting into a stable, airy texture.
- Baking powder
- Releases gas during baking so the layers rise and stay light.
- Sugar
- Sweetens the cake and, cooked into syrup, forms the body of the frosting.
- Walnut meats
- Add crunch and nutty flavour to the filling.
The step that matters
Cooking the syrup to the right stage. Sugar syrup must reach the exact stage described, honey-like for the first cup and thread-stage for the rest, because the sugar concentration determines whether the frosting sets soft and glossy or runs or turns grainy. Pouring hot syrup into the egg whites while beating keeps the foam stable.
