Plum Jam

1 Sep

This year has been a wonderful year for the plums!  My tree has more on it than I’ve ever seen before. They are big and beautiful!  I had to make jam.

This plum comes from my mother’s house, and it’s got a great tasting flesh, but, sadly, the skin is tough and bitter.  All the jam recipes I’ve ever seen say to use the skin, so I had to make some adjustments.  Pit about three pounds of plums and put them in a pan with 1/2 cup of water.


Simmer until they are very soft and the skins nearly free of flesh.

Then run the plums through the colander until you have 4 1/2 cups of the plum sauce.  From this point, it’s following the directions for any jam.

This is also the time to get your flats, rings and jars ready by sterilizing them and keeping them hot.

Add the pectin and cook over a medium high heat until it comes to a full rolling boil.  More than any other kind of jam, this one wants to stick and scorch, so it is important to stir it constantly.sure jel collage w

When it gets to the full roiling boil, add the sugar all at once and return to the full rolling boil, still stirring constantly.

Process them in a hot water bath for five minutes.

Enjoy some of the best jam you’ll ever have.  I make no claims how this process will work with other varieties of plums.
