Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rolled Jelly Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the sugar, flour, eggs, milk, and baking powder until smooth.
Bake and fill
Pour the batter into a flat pan and bake until lightly golden.
Allow the cake to cool slightly, then spread with currant or lemon jelly.
Roll and serve
Roll the cake up tightly and slice to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Trap air and set into the structure of the sponge as it bakes.
- Flour
- Forms the gluten network that gives the cake its body.
- Sugar
- Sweetens the cake and helps keep it tender.
- Baking powder
- Releases gas during baking so the batter rises and lightens.
- Milk
- Adds moisture that keeps the batter loose and the crumb soft.
- Currant or lemon jelly
- Adds sweetness and a fruity, tart flavour inside the rolled cake.
The step that matters
Roll the cake while it is still slightly warm. Warm sponge is flexible, so it can bend without splitting. Once it cools fully, the crumb stiffens and cracks when rolled, so the cake should be rolled soon after the jelly is spread.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, flour, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
