I ran out of jam this morning which means that I cannot make for lunch tomorrow what I normally make. So I need to make some.
I put ten ounces of frozen fruit and one cup of sugar in a heavy saucepan. Mine is enameled cast iron. I then set it on medium low heat (three on my electric stove top) and cook for about three quarters of a hour to an hour. I do stir it occasionally with a wire whisk. And I do watch towards the end to make sure it does not burn.
Then it goes in a jar and sits in the refrigerator. It is really that easy. I do not have to skim the scum off or anything. I do have to watch a little bit so it does not burn but that really happens only when it has cooked to long and become too thick. Very yummy! Especially on peanut butter and jam sandwiches on homemade bread. It makes me smile.
