So, at the moment I make the fruit or veggie puree, freeze it, defrost it over night, take it out of the fridge and zap it for 10 seconds in the microwave so it is approx. room temperature, stir it well (to avoid hot spots) and then feed it to dd.
However, someone has told me I am supposed to reheat the puree to max temperature and then let it cool down before feeding it to dd? What are others doing?
