Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boston Velvet Cake
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
Cream the butter and gradually add the sugar while beating constantly.
Add the yolks of the eggs.
Mix and sift the flour, baking powder, and salt.
Add the dry mixture alternately with the cold water to the butter mixture.
Cut and fold in the lightly beaten egg whites.
Bake
Turn the mixture into a well-buttered shallow cake pan.
Sprinkle the shredded almonds over the top.
Bake for 35 minutes in a moderate oven at 350°F (175°C).
This cake should not be frosted.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- Eggs
- Yolks enrich and bind the batter; whites, folded in, lighten it and help it rise.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Sugar
- Sweetens the cake and helps tenderize the crumb when creamed with butter.
- Corn starch
- Softens the flour's gluten, giving the cake a finer, more delicate texture.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air beaten into the whites. Stirring hard would deflate the batter, and the cake would bake up dense and flat instead of light.
