What is jam? jam is pretty much a preserve, what is a preserve? well, when you cut up some fruit and cook it gently until it is soft so that it realeses all of it delicous juices and evaporates, by this time its approximately 3 hours including the prep time, then you add real cane sugar, turning up the heat beacause it is about to gel and we are ready to can this baby. We get so excited about making our spreads that we infused that love into every singe spoon full. so when you get our jam its is going to be lumpy, chunky with the whole fruit in it.
