If you have a baby cooker, set the baby cooker and steam.
If you are steaming with a steamer basket, place the cut up apples in the steamer basket over a pot filled with water and turn the heat to high and cover the pot. Should take about 10-15 minutes.
Remove the apples and place in your blender.
Blend until you get a nice puree consistency and keep adding water teaspoon by teaspoon if you need it to be more smooth.
