Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Roly-poly Pudding
Ingredients
Directions
Prepare the dough
Combine flour, suet, salt, sugar, and baking powder in a bowl. Mix well.
Add enough butter milk or water to form a stiff paste.
Turn the mixture onto a floured surface and roll it into a thin sheet.
Assemble the pudding
Grease a pudding bowl with dripping.
Line the bowl with the paste, cutting the edges evenly.
Place a spoonful of jam at the bottom. Cover the jam with more paste.
Repeat layering jam and paste until the bowl is full, finishing with a piece of paste on top.
Wet the edges to help it adhere.
Cover with buttered paper.
Steam and serve
Place the bowl in a pot with ½ inch of boiling water, cover tightly, and steam for 2 hours.
Carefully turn out the pudding when done.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 structure of the paste that encloses the jam.
- Suet
- Adds fat that keeps the paste tender and rich as it steams.
- Baking powder
- Releases gas that helps the paste rise and lighten.
- Jam
- Provides sweetness and fruity flavor that soaks into the paste as it steams.
The step that matters
Wet the edges before covering. Moistening the paste edges helps the layers seal together, so the jam stays enclosed and the pudding holds its shape during steaming rather than leaking or collapsing.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
