There are tons of raspberries in our Moldovan backyard that end up in the blender for the most fragrant, delicious jam you would lay tongue on! No heat process, just sugar and berries. Touted to heal all sorts of colds and weaknesses...I assume it keeps a lot of its vitamins intact, since it is not heated....Who knows? If anything, it is very tasty. Especially over a plain yogurt sponge cupcake. Yum.
