Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Baked Jam Roll
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Preheat the oven to 400°F (200°C).
In a bowl, mix flour, dripping, brown sugar, baking powder, and salt to make the pastry.
Roll out the pastry to about ½ inch thick.
Fill and roll
In a separate bowl, mix the jam with 2 tablespoons of water and 2 tablespoons of sugar.
Spread the jam mixture evenly over the pastry.
Roll the pastry up carefully into an oval shape, ensuring it is tightly packed.
Fold the ends of the roll up and cover them with the flap of the roll, sealing with a little water if necessary.
Bake
Bake in the preheated oven for 10 minutes.
Reduce the temperature to 350°F (175°C) and bake for an additional 50 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the pastry's structure, holding the roll together while it bakes.
- Dripping
- Adds fat that keeps the pastry tender and rich.
- Brown sugar
- Adds sweetness and helps the pastry brown.
- Baking powder
- Releases gas during baking so the pastry rises and lightens.
- Gooseberry jam
- Adds sweetness and moisture to the filling inside the roll.
The step that matters
Rolling and sealing the roll. A tightly rolled pastry with sealed ends keeps the jam from leaking out and spreading during baking. Loose rolling or open ends let the filling escape and burn on the tin.
Swap the gooseberry
How well each one fits the dish's main ingredients (flour, sugar):

- Gooseberrythe original
Fit is the average pairing score against flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
