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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the paste once moistened and steamed.
- Butter
- Fat that coats flour strands, keeping the crust tender and short.
- Eggs
- Bind the paste and enrich it, helping it hold together.
- Rump steak
- Main filling, cooked gently by the steam inside the sealed crust.
The step that matters
Ensure the pudding is sealed well. Steaming relies on a tight seal so steam stays trapped and cooks the filling evenly, while keeping boiling water out of the basin.
“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.
