There really isn't much to this recipe just carrots and water. Just take a bag of frozen carrots (I used crinkle cut but it doesn't matter) and boil in water until soft and gummable. Drain and place in blender or food processor and pulse until smooth. If it is too thick then thin with water. If too thin then thicken up with cereal.
Place pureed carrots in ice cube trays. You can freeze them and then thaw cubes as needed for feeding.
