I am with headwreck. I don't parboil mine and use the plastic bag method, it cuts out so much mess. Chuck them in a plastic back with enough oil to coat, I like paprika, garlic, salt and pepper on mine, you need enough paprika so you can see a slight red colouring but not too much (although I have to temper mine for the kids), smoked paprika is nice too. If you have one of those plastic clips for resealing frozen food bags stick that on the plastic bag to avoid leakage and then give it a good shake. I reckon gas mark 4 or 5 is best for cooking as if you are cooking from raw you don't want to burn them before they are cooked through. MMMMMM Yummy, am getting hungry just thinking about it, but I have dough rising next to me for our home made pizza tonight - also yummy.
