I've got frozen pastry (hopefully coming via Ocado) and sausagemeat to make my own sausage rolls this year - DD has egg allergy and I think she would love them so making my own is the only option. Shall I make them up, cook and then freeze to defrost/reheat them when needed? I want to make them on the 23rd and serve them to friends on the 24th and in laws on the 26th. Or should I just put them in a tupperware box in the larder and reheat them?
