A sweet and slightly tart seasonal blueberry jam. This jam is simple in that it doesn't take long to make and only requires 4 ingredients. Make this when blueberries are in season, or substitute another seasonal fruit.
In a medium pot over medium-low heat, combine blueberries, lemon juice, sugar, and salt.
Bring the blueberry mixture up to a simmer, stirring frequently. After about 10 minutes, the blueberries will start to break down.
Continue cooking until a majority of the blueberries have broken down. Use a strong fork or a potato masher to mash up any remaining berries.
When you have a smooth jam, remove the pot from the heat and allow the jam to cool.
Once the jam is cool, transfer to a jar and store in the fridge up to 3 months.
Makes 1 small jar.
