Preserved Fruit, Without Sugar

Oven, in the book's wordsA very slow oven

Ingredients

Directions

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

Prepare

  1. Pick off the stalks from the damsons and place them in wide-mouthed glass bottles, ensuring they are whole and without blemish.

  2. Shake the bottles well to ensure they are filled properly.

  3. Stop the bottles with new soft corks, but do not seal them too tightly.

Bake and store

  1. Place the bottles in a very slow oven at 300°F (150°C) for four to five hours.

  2. Remove the bottles when the fruit begins to shrink, indicating they are thoroughly warm.

  3. Before the bottles cool, drive the corks in tightly.

  4. Store the bottles upside down in a rack or basket; they will keep for several years.

The step that matters

Drive the corks in before the bottles cool. As the bottles cool, the air inside contracts and creates a partial vacuum. Sealing the corks while the bottles are still warm lets that vacuum draw the cork in firmly, helping keep the bottles airtight for storage.
