The rhubarb in this recipe makes a LOT of the rhubarb mixture. BUT, you can use this for tonnes of recipe too! This morning we topped our pancakes with it, and the kids also made overnight oats too! The remaining mixture was put into the mini muffin tin, covered in clingfilm and frozen into ice cubes. Once frozen, i've just popped them out and into little freezer bags. They are brilliant for smoothies or to cook with when i'm making rhubarb dishes. Zero waste which is great!
