Why it works: Barley and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 128 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Chocolate 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 fat and brown sugar together.
Add the egg yolks, corn syrup, and melted chocolate, and beat well.
Sift the dry ingredients together and add them alternately with the milk.
Add vanilla and fold in the stiffly beaten egg whites.
Bake
Bake in a loaf or layers in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley flour
- Provides the structure that holds the cake's crumb together.
- Eggs
- Egg whites trap air for lift, and yolks add richness and help bind the batter.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Corn syrup
- Adds sweetness and moisture, helping the cake stay tender and moist.
- Chocolate
- Adds deep flavor and color to the cake.
The step that matters
Fold in the stiffly beaten egg whites. Folding gently keeps the air beaten into the egg whites, which gives the cake its lift. Stirring or deflating the whites makes the cake dense and flat.
