You mentioned your strawberry recipe being very sweet. Did it have you ad some lemon Juice? I find that adding a 1/4 to 1/2 cup per batch really "brightens" up the berries and makes them not so sweet. I love jams on the tart side anyway. I hate the store bought ones that are just like eating sugar. However your idea of "mixing" it up a bit is great. You get some great combos with berries and some great flavors. I love Straw/blueberry and straw/rhubarb. YOu can be creative with so many flavors. I also tried the spiced blueberry jam someone posted on here. I was way yummy. I added a little vanilla when it was done cooking and with the cinnamon nutmeg and clove it was mucho nummy
