Ingredients
Directions
Prepare the dough
Preheat your steamer.
In a bowl, mix flour, baking powder, and salt. Cut in butter until crumbly. Stir in milk to form a dough.
Roll out the dough to 1 inch thick.
Fill and roll
Spread preserves evenly over the dough. Roll the dough tightly to enclose the preserves.
Grease a dish and place the rolled dough inside.
Steam and serve
Steam for 1.5 hours.
Turn out onto a platter and serve with boiled sauce.

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 dough that holds the filling inside the roll.
- Baking powder
- Releases gas during steaming, helping the dough rise and turn light.
- Unsalted butter
- Cut into the flour to create a crumbly texture and tender layers.
- Milk
- Hydrates the flour so the mixture comes together as a dough.
- Preserves
- Provides sweetness and fruity flavour in the filling, and moisture as it softens.
The step that matters
Rolling the dough tightly around the preserves. A loose roll can let the filling leak or leave air gaps during steaming. A tight, even roll keeps the filling enclosed and the layers consistent.
