Instructions
Prepare the blueberries
Rinse the blueberries under cold water and remove any stems or debris. Gently pat dry with a clean towel.
Pro tip: Use ripe blueberries for the best flavour and natural sweetness.
Cook the blueberries
In a large saucepan, combine the blueberries and lemon juice. Cook over medium heat, stirring frequently, until the blueberries begin to release their juices, about 5 minutes.
Pro tip: Crush some of the blueberries with a spoon to help them break down faster.
Add sugar and pectin
Stir in the sugar and lemon zest. Sprinkle the pectin over the mixture and stir to combine. Bring to a boil over medium-high heat, stirring constantly.
Pro tip: Ensure the mixture reaches a full, rolling boil that can't be stirred down.
Boil the mixture
Boil for 1 minute, then remove from heat. Skim off any foam that forms on the surface.
Pro tip: Use a metal spoon to skim off foam for a clearer jam.
Test for setting
To test if the jam is set, place a small spoonful onto a chilled plate. Let it sit for a minute and push it with your finger. If it wrinkles, it's ready.
Pro tip: If the jam isn't setting, boil for another minute and test again.
Jar the jam
Ladle the hot jam into sterilized jars, leaving 1/4 inch (0.6 cm) headspace. Wipe rims clean, place lids on, and process in a boiling water bath for 10 minutes.
Pro tip: Ensure jars are fully submerged in water during processing.
