Prepare the filling

  1. Soak the prunes overnight.

  2. In the morning, cook the prunes until tender, remove the pits, and shred with a fork.

Make and roll the dough

  1. In a bowl, mix the flour, baking powder, sugar, salt, and butter to form a soft dough.

  2. Roll out the dough to about ½ inch thick.

  3. Spread the stewed prunes over the dough and roll it up tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Prunes
Provide the main filling, adding moisture and a sweet, tender texture when stewed.
All-purpose flour
Forms the structure of the dough that holds the rolled filling together.
Baking powder
Releases gas during steaming, helping the dough rise and turn light.
Butter
Adds fat, which tenderizes the dough and gives it a richer flavor.
Lemon juice
Adds acidity that brightens the sweetness of the prune filling.

The step that matters

Roll the dough up tightly around the filling. A tight roll keeps the prune filling inside the dough during steaming. Loose rolling lets filling escape and leaves gaps in the finished roll.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, flour, butter):

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