You’ll need:

Fruit or Veggie of Choice such as apples, banana, carrots, sweet potato, etc.
In this instance, I’ll pick Carrots.

1 Peeled carrot (or more if desired)

Covered pot/pan

Steamer tray

Water, enough to touch the underside of steamer pan

Food processor or masher

Directions:

Peel and chop the carrot into small pieces and place on steamer inside the pot.

Turn stovetop and steam until carrots can be pierced easily with a fork.

Mash steamed carrot pieces until thoroughly pureed, no hint of a chunk should remain.

Add fresh water to create desired consistency.

Divide what isn’t eaten into ice cube tray compartments, cover with plastic wrap and freeze for future use.

Easy Peasy!  Repeat process with other fruits/veggies.
