Cut the apple into 1 cm cubes, and cut the sweet potatoes into bite-sized pieces.
In a heatproof container, add the apple and sweet potato, and microwave for about 3-4 minutes. Once the ingredients are tender, add the butter and mash them. Add the raisins if desired.
Story Behind this Recipe
It's very easy to make and it's perfect for lunch for my child and I. It's a favorite within our family. I like to pack in our lunchboxes too.
If you are putting it in a bento box, place a small amount of the mixture onto plastic wrap and squeeze to make a shape. It may taste good if you wrap it with gyoza skin and pan-fry it in butter. It's not too sweet, so you can adjust the amount of the sugar to your preference.
