Like with jam, certain fruits are more suitable than others for fruit leather. For instance, I once tried to make fruit leather from watermelon, which didn’t work as well.
Here I used both red and yellow plums. Other fruits that work well include apples, apricots, bananas, berries, cherries, gooseberries (you will need more sugar), mangoes, nectarines, peaches, pears, pineapple, raspberries and strawberries. Some fruits, such as blueberries, you can use in combination with the more suitable fruits. You could also add small amounts of flavouring, such as juice from freshly minced ginger, ground cinnamon or nutmeg, maple syrup, vanilla extract or paste. You could also add seeds to the leather sheets.
If you have a dehydrator, fruit leather is even easier to make.
