This is very simple and old recipe. We usually use a kind of plums that grows in area of south Austria, Hungary, Slovenia and Northern Croatia and we call this plum “bistrica”. It is small; the surface is like foggy, and inside is dark yellow and red/brown around stone. It is very sweet so you don’t need too much sugar. It is kind of wild plum so we don’t use any chemistry to prevent diseases. It is very healthy fruit. I named the jam Christmas because we usually start to eat it around Christmas. The ingredients also contribute to the name.
- Wash the plums thoroughly. Break them in halves and remove stone. Put them in a pot and add sugar, cinnamon and cloves. Stir well and let it stay 5-6 hours.
- After that, put them onto strong fire and boil 4-6 minutes stirring well all the time to prevent burning.
- In the meantime, put glass jars into an oven and heat them to 100°C.
- When cooking is done put the jam into glass jars and close. Leave at least 1 cm space between cover and jam. Keep it in dark and cool place up to 8 months.
