Why it works: Vanilla and plum match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 171 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Jelly Cake
Ingredients
Directions
The book says “a slow 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 sugar together until light.
Slowly add the milk while beating hard.
Beat in the egg yolks until light.
Add the flour, baking powder, and vanilla, mixing well.
Fold in the stiffly beaten egg whites last.
Bake and assemble
Pour the batter into cake tins and bake at 350°F (175°C) until done.
Once cooled, layer the cakes with plum jelly and sprinkle the top layer with powdered sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
- Eggs
- Yolks add richness and structure; whites, beaten stiff and folded in, provide lift and airy texture.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
- Milk
- Adds moisture and helps form a smooth, tender batter.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that gives the cake its lift. Folding gently keeps that air in; vigorous stirring deflates the foam and leaves a dense cake.

Fit is the average pairing score against butter, sugar, egg, milk, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
