  • 750 g/ 1.7 lbs rhubarb
  • 750 g/ 1.7 lbs raspberries
  • 500 g/ 1.1 lbs/ 2 1/2 cups granulated sugar
  • 30 g/ 1 oz apple pectin powdered (See note)


  • If you want to remove the raspberry seeds, read the blog post for instructions. However, I don't do it, too much trouble.
  • Start by preparing your jars. I had enough jam to fill 4 large jars, if your using smaller you will probably need about 8. Wash and sterilize them, including the lids, and place them on a clean kitchen towel until ready to fill.
  • Clean and chop the rhubarb into small pieces.
  • Place the rhubarb in a very large pot, bring to a boil and cook for about 5 minutes or until soft, stirring from time to time.
  • In the meantime mix 100 g/ 3.5 oz of the sugar with the pectin in a jar. Place the lid on and shake very well to ensure that everything is mixed well. (Note)
  • Add the raspberries to the rhubarb pot and puree the mixture with an immersion blender. Add the sugar-pectin mixture, mix very well and bring to a boil while stirring continuously.
  • When it starts to boil, set the timer and cook for 3 minutes while stirring all the time.
  • Add the rest of the sugar, bring to a boil again and continue boiling for another 2 minutes while stirring all the time.
  • Transfer immediately to the prepared jars.
  • Can the jam if desired. Either in a canner or in a waterbath.



Make sure that you read the packet's instructions on how to use the pectin, the method might be different than the one I use. It is better to follow the packet's instructions if they differ from the ones I give.
