Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Fudge Cake
Ingredients
Directions
Prepare the batter
Preheat the oven to 350°F (175°C).
Sift flour once, measure, then sift with baking powder, baking soda, and salt three times.
Cream shortening thoroughly, add sugar gradually, and cream until light and fluffy.
Add egg yolks and melted chocolate, then alternately add flour and milk, a small amount at a time, beating until smooth after each addition.
Stir in vanilla and fold in stiffly beaten egg whites.
Bake and assemble
Pour batter into two greased 9-inch layer pans and bake for 30 minutes.
Once cooled, layer the cakes and cover the top and sides with fudge frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and, with the whites, add structure and lift as the cake sets.
- Shortening
- Creamed with sugar to trap air, giving the cake a tender, fine crumb.
- Sugar
- Creamed with shortening to aerate the batter and add sweetness and browning.
- Unsweetened chocolate
- Provides the chocolate flavor and deep color of the cake.
- All-purpose flour
- Forms the cake's structure as its proteins set during baking.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps the cake rise.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold the air that lifts the batter. Folding gently keeps that air in; stirring or overmixing deflates it and leaves a dense cake.
