Pulwal Preserve

Ingredients

Directions

Prepare the pulwals

  1. Peel, slit, and remove the seeds from the pulwals. Soak them in cold water and wash them.

  2. Parboil the pulwals in clean water, then place them in a flat dish to cool.

Make the preserve

  1. Prepare a syrup by combining the sugar and pounded green ginger in a pot.

  2. Add the pulwals to the syrup and simmer until the syrup thickens.

  3. Remove the pulwals when they turn brown, but keep the syrup boiling until it reaches the right consistency.

  4. Return the pulwals to the syrup. If the syrup appears thin or starts to ferment, reboil it two or three days later.

What each ingredient does

Pulwals
Form the main body of the preserve, softening as they cook in the syrup.
Sugar
Forms the thick syrup that preserves the fruit and gives it sweetness.
Green ginger
Adds a sharp, aromatic flavor that balances the sweetness of the syrup.

The step that matters

Reducing the syrup to the right consistency. Sugar syrup thickens as water evaporates and concentrates, and it must reach enough sugar concentration to keep the preserve from fermenting. Removing the pulwals at the right moment and boiling the syrup further helps achieve this. A thin syrup can ferment, which is why the recipe calls for reboiling.
