Has anyone got useful information? I've looked at a delivery service where you get frozen portions. What do you do with them? I have no experience at all of cooking/defrosting meat so this is all strange to me. Mine are a complete pain with not liking any premade sachets or tins or trays. They only eat a mouthful or so and whinge for more. One in particular that is. No tooth problems, they've been checked. Thanks.
