1 Peeled, ripe Banana, cut up ( I cut mine in half and scrape out the banana seeds, I don't know if it matters.)
1/4 cup of water. (less if you want it a bit thicker)
Puree the banana with water until smooth.
Spoon the puree into the ice cube trays and freeze until solid. Once its frozen solid place the food cubes into the ziploc bag and make sure to label the bag with the type of food and date you made it. It can keep frozen for up to 30 days and in the fridge for up to 3 days.
To serve - take your serving out of the freezer and place in a glass dish or BPA free plastic one and place in the fridge for a few hours. If you're in a hurry, place the food in a sealed container (ziploc bag or cup) and place in a bowl with hot water. You can change the water a few times until it's warm. Not HOT.
