Blueberry Grapefruit Jam

I have a freezer full of summer fruits; gathered in their peak and frozen to preserve freshness. It is my own secret garden. This jam combines the summer goodness blueberries hold, with beautiful winter grapefruit. I love it spooned onto toast, but I also have been using it as topping for cheesecake, filling for my homemade pop tarts,and as a delicious swirl in my morning yogurt.
