Preserved Pears

Ingredients

Directions

Prepare

  1. Peel the pears, cut large ones into quarters, and remove the cores.

  2. Weigh the fruit and use an equal weight of sugar.

Make the syrup

  1. Dissolve the sugar in just enough water to wet it.

  2. Add ¼ ounce of isinglass dissolved in warm water to the sugar mixture.

  3. Once the sugar is dissolved, make the syrup as directed for preserved peaches.

Cook and pack

  1. Cook the pears in the syrup until they look clear when held to the light, about 1.5 hours.

  2. Remove the fruit and place it on broad dishes.

  3. Strain the syrup, then when lukewarm, pour it over the fruit in jars.

  4. Cover the jars with brandy paper and seal tightly.

What each ingredient does

Pears
Provide the fruit that is cooked and preserved, becoming tender and translucent in syrup.
Sugar
Sweetens the fruit and, at high concentration, helps preserve it by drawing out water.
Isinglass
A gelatin-like protein that helps clarify the syrup and gives it a light set.

The step that matters

Cooking the pears until clear. Fruit must cook long enough for syrup to penetrate and the flesh to turn translucent, which signals sugar uptake. Undercooked pears may spoil, while overcooking makes them break apart.
