My first plum jam

Since I had to make the Zucchini cake but already cut and pitted the plums I was going to make something out of them too. I know, I know, it doesn't look very pretty but it tastes that much better!hihi I made only 4 glasses full, it's not much but I had to use the plums and on the other hand our pantry is already full with self made jam and it would have burst if I  had done more...

Recipe

Ingredients:

1kg Plums

1/2 Teaspoon Cinnamon

200g sugar

Tablespoon Rum

Preparation:

Preheat oven to 300F(150C).Wash, cut and pit the plums and prepare the glasses. Cook the plums until they are tender and then put them in a casserole that fits your oven. Insert 50g of the sugar and the cinnamon. Put the casserole in the middle row of your oven and keep the oven a little gap open. Without stirring the plums let them in the oven for 30 minutes then take them out and put another 50g of sugar in the plums. Do so until all the sugar is used. And then you can fill your glasses. The skin of our garden plums is very hard so I sieved it first and then fill the glasses.
