Boston Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Cream together the sugar and butter.

  2. Break in one egg and beat well.

  3. Sift the flour three times, adding the salt, baking powder, and corn starch the last time.

  4. Add a little of the flour mixture to the creamed mixture.

  5. Stir in the second egg and the milk.

  6. Gradually add the remaining flour and the vanilla.

Bake and finish

  1. Bake in a moderate oven at 350°F (175°C) in a loaf or two layers.

  2. If using layers, frost with chocolate frosting and cream filling.

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 trap air and give the cake a tender, rich crumb.
Eggs
Bind the batter and add structure and richness as the cake sets in the oven.
Pastry flour
Provides the main structure of the cake while staying tender because of its lower protein.
Corn starch
Softens the flour's gluten, producing a fine, delicate crumb.
Baking powder
Releases gas in the oven so the cake rises and becomes light.
Milk
Adds moisture and hydrates the flour so the batter flows smoothly.

The step that matters

Adding the flour mixture gradually. Adding flour in stages after creaming and egg addition keeps the batter smooth and emulsified. Overmixing once the flour is in develops gluten, which can make the cake tough.
