I've been merrily making up pots of veggies and fruit for LO and freezing. To defrost, if I remember, I put them in the fridge over night then take the cold edge of at feeding time by floating in hot water. If I forget to defrost over night, I do the same method (float in hot water ) until the block melts completely. Since then I bought the Anabel Karmel (?) book and it states to always heat up food (say in the microwave) until piping hot then allow to cool. I understand why this has to be done with products containing meat for example but is my technique safe for the fruit and veggies? I understand this is a total noob question probably done to death but everything I read is always contradicting.
