Mix the chopped berries with sugar and cinnamon powder and leave aside for 8 hours, occasionally stir if possible. I didn’t stir mine as I kept them in the night.
Place the above mixture (the berries would have left water and sugar quite melted) in a steel vessel (its important for it to be non reactive so please dont use a non stick one for this) and bring it to a boil over medium heat.
Add the lemon juice and let it boil for 5 minutes stirring in between to avoid spillage. Set aside for 24 hours.
After 24 hours, bring the mixture to a boil again on high heat, now add butter to the same.
Continue boiling the mixture for next 5 minutes continuously stirring.
Put the jam into sterile jars. Close it well and process for 10 minutes in a boiling water bath.
And your jam is ready to be devoured.
If you make this, share a picture with me on twitter, instagram or Facebook? I would love to hear what you have to say about it !”
