Using a food-mill (this is the one I got) to make the blackberry puree was surprisingly fast and easy. I am basically in love with the food mill now, and pretty much want to use it for everything.
blackberry-white nectarine jam
In a large saucepan, combine fruit and sugar. Bring to a boil over medium-high heat, watching and stirring to avoid boiling over. Add cinnamon and lemon zest/juice and stir some more. After the mixture begins to thicken (perhaps 5-10 minutes longer), add the pectin and allow to boild vigorously for at least five more minutes.
