Here in Alabama, u-pick is really coming into its own. Today we picked nearly 2 gallons of blueberries at an awesome local farm (Bear Mountain) that grows its berries according to organic principles (that means, they haven’t paid the federal government for the privilege of the “certified organic” label!)
But you only really get the benefit of the full awesome flavour and colour of fresh, seasonal fruit if you avoid cooking them into oblivion, which you will with conventional pectin.
This is why I always, and only, recommend Pomona’s Universal Pectin (Amazon link). Unlike conventional pectin you can make jam with NO added sugar, or with alternative sweeteners such as honey or maple syrup.
Once you go Pomona’s you will never go back to adding more sugar than fruit to your preserves!
