Notes
SWEETNESS The ratio of rhubarb to apple is completely variable, just leave the other ingredients the same. I personally feel that a ratio of 2:1.5 rhubarb to apple is spot on though we all have different tastes. Increase or decrease the apple ratio as you prefer and by all means if you feel you want a sweeter result, add a dash of raw honey. I would recommend making this recipe and seeing what you think, it is surprisingly sweet as it is. STORAGE Will keep well when stored in an airtight container in the fridge for up to 6 days.
