It is indeed fine to do this so long as you are cooking it to properly hot in between the two freezes. It is defrosting to room temp and then refreezing that can be dodgy.
If I'm making something intending to freeze most of it I sometimes buy quorn mince from the fridge section rather than the freezer section so that it only gets frozen once, but I know it's not really necessary to do this.
Excellent! Now I just need to look up some exciting recipes and get cracking with the cooking. I will definitely be cooking to a high temp Adrift - am very anal with food and always end up overcooking then worrying about carcinogenic burn on food God I hate cooking! I'd much rather do three hours of ironing shirts and creased denim than an hour in the kitchen! Do you fancy stocking my freezer too lapsed!?
