Blackberry Sweetmeats
Ingredients
Directions
Cook the fruit
Place the blackberries in a porcelain-lined kettle over moderate heat until enough juice is released to prevent scorching.
Boil the fruit until perfectly tender, about 10 to 15 minutes.
Add sugar and jar
Carefully mix in the sugar without bruising the fruit.
Do not boil again; as soon as the sugar is dissolved, fill jars quickly.
Cover the jars immediately.

What each ingredient does
- Lawton blackberries
- Supply the fruit flavour, colour and natural pectin that help the preserve set.
- Granulated sugar
- Sweetens the fruit and, with cooking, helps thicken and preserve it.
The step that matters
Do not boil again after adding the sugar. Once sugar is dissolved, further boiling can darken the preserve, break down the fruit and weaken its set, so the jars should be filled promptly.
