I love homemade pizza - after many years I've finally got a recipe I love.
I usually make the dough, let it rise twice, then roll into a ball and freeze - usually in greaseproof, as I've got tons of that lying around that needs used up (no idea why I bought loads of it, I rarely use it).
Then I defrost beside the aga (takes about 3 hours) or in the fridge (takes about 8 hours), then roll and make the pizza up. My recipe is passata, chilli oil, garlic, mixed herbs mixed for the base, then topping of your choice.
Occasionally I make up full pizzas and freeze, but they don't fit in the freezer well - I think you need a flat space in the freezer or something you can lie them on.
If they are burning, it sounds like the temp may be too high - I find lower does pizza better, like 180 - 200 rather than the 230 lots of people suggest.
