Step 1

In a medium pot, add all ingredients and cook on high heat, stirring from time to time.

Step 2

Once it comes to a rolling boil, cook about 5 minutes, making sure to stir often. Your rhubarb (and raspberries) will start breaking down. That's good!

Step 3

Reduce heat to low and continue cooking the fruit mix for 20 minutes, until it thickens slightly and the fruit resembles jam texture.
