This Blueberry Jam quick and easy without pectin is the perfect recipe for spread it on toast for breakfast or use it in dessert recipes.
|4 lbs fresh blueberries||3 cup granulated sugar||1 whole lime, juice, zest||4 pinch salt|
Add lime juice, and zest then low heat to simmer, stirring often, until thickened and mixture clings to a spoon about 20 minutes, skim any scum that rises to the surface.
Use one spoon a little jam on to the cold plate, let set for 1 minute then push the blob of jam with a finger, one the surface of the jam wrinkles, then it has set. If it is still runny then continue to cook for a few more minutes until testing again. Ladle finished hot jam into clean sterilize jars, let cool completely to room temperature, storing in the fridge up-to one month.
