Plum Preserves

Oven, in the book's wordsA very cool oven

Ingredients

Directions

The book says “a very cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the jars

  1. Combine plums and sugar in a jar, ensuring sugar is added after the fruit without shaking it down.

  2. Seal the jars with a bladder and secure with paper or cork.

Cook and rest

  1. Place jars in a pan of cold water with hay between them, and boil gently for about 3 hours.

  2. Alternatively, bake in a cool oven at 300°F (150°C) for 4 to 5 hours.

  3. Leave the plums in the syrup for a few days before serving.

What each ingredient does

Plums
Provide the fruit that is cooked and preserved in its own syrup.
Sugar
Sweetens the fruit and draws water out to form a syrup that helps preserve it.

The step that matters

Heat gently. Gentle heat cooks the plums through without breaking them apart or forcing the sealed jars to boil hard and loosen. Slow cooking also lets the sugar syrup penetrate the fruit evenly.
