Has anyone ever frozen mashed bananas or avocados in ice cube trays? I have a load of bananas and avocados at home right now, which I know my family will not be able to eat before they go bad. Can they be mashed and frozen (separately, of course) in ice cube trays as baby food? It's a silly question, I'm sure, but we're just starting this whole solids thing and I feel so clueless!
