After enjoying Bulldog's Strawberry Pale Ale immensely I am trying an AG version from the Greg Hughes book. It doesn't say zip in the book hopw to prepare them, it just says add them, I have googled the subject quite a bit and most seem to use frozen ones in the hope of good hygiene and the ice crystals rupturing cell walls and increase flavour, anyone got anymore tips or experience ? Should I puree them, cut them up small pieces or slices ? There is 3,5 kg going into a 23l batch.
