Ingredients

Directions

Prepare the pears

  1. Peel, quarter, and core the pears.

  2. Weigh the pears and pack them closely into an earthen jar.

  3. Place the jar in a saucepan of boiling water and let it remain until the fruit is soft.

Make the syrup

  1. In a separate pot, combine an equal weight of sugar with 1 pint of water for each pound of sugar.

  2. Heat the sugar mixture and skim until it forms a clear syrup.

Cook and store

  1. Add the pears to the syrup and stir frequently until it boils.

  2. Once boiling, stir constantly and boil for 20 minutes.

  3. Partly cool the jam and then store it as directed.

What each ingredient does

Perfectly ripe pears
Provide the fruit, flavor and pectin-bearing body that gives the jam its texture.
Sugar
Sweetens the jam and helps it thicken and keep as it cooks down.
Water
Dissolves the sugar into a syrup that the pears cook in.

The step that matters

Boil the jam constantly for 20 minutes. Stirring constantly keeps the fruit from scorching on the bottom of the pot. Sustained boiling drives off water and concentrates the sugar so the jam sets properly.
