Paleo raspberry and blueberry jam

Found this recipe on paleomg.com and it is so delicious. I can eat it by the spoonful as a special treat but even better to put on some porridge in the morning or on some pancakes.

Ingredients
makes approx 250 g
480 ml frozen raspberries
240 ml fresh blueberries
160 ml honey
juice of 1 lemon

Place a saucepan over medium heat. Add the frozen raspberries to cook until they are heated up and the start to get juicy. Then add the blueberries, honey and lemon juice.
Mix and cook for about 5-7 minutes then reduce the heat and cook on low for another 15 minutes until everything has broken down into a well combined mixture. The longer you let it simmer on low the thicker your jam is going to be.
