Place fruit and juice in a small saucepan and bring to medium heat.
Once bubbling, reduce heat slightly and use a wooden spoon to muddle and mash the fruit.
Continue cooking over medium-low heat for 10-12 minutes, occasionally mashing fruit to combine. Turn off heat and add optional add-ins at this point (cinnamon, ginger, sugar, chia seeds).
Remove from heat and transfer to a clean jar or container to cool thoroughly. Store in the fridge up to 1 week or freeze in ice cube molds up to 1 month. Reheat to serve with oats, pancakes, waffles, french toast, and more!
