Recipe Introduction
Sweet spicy blueberries are high in pectin so they are the perfect fruit for jam making. Fresh blueberries are available during the summer and early autumn months.
List of Ingredients
- 4 lb blueberries
- 7 cups sugar
- juice of 2 lemons
- pinch of salt
Instructions
- Put the blueberries into a nonmettalic bowl with half of the sugar, all of the lemon juice, and the salt. Stir to mix, cover, and leave to stand for about 5 hours or overnight.
- Pour the contents of the bowl into a preserving pan. Add the remaining sugar, and stir over low heat, with a wooden spoon, until the sugar has completely dissolved.
- Increase the heat and boil the mixture rapidly, without stirring, for 10-12 minutes or until it reaches setting point. Remove the pan from the heat to test. The candy thermometer should read 220 F. If you do not have a candy thermometer, test for setting with the cold plate test.
- With the pan off the heat, lightly skim off any froth from the surface of the jam, using a long-handled metal spoon.
- Immediately pour the jam into warmed sterilized jars, to within 1/8 inch of the tops. Seal the jars and label.
