This is something I'll be resurrecting soon after about a year's absence. I'm planning on sticking to my tried and trusted BBC Good Food recipe for the dough, only using pasta flour in place of strong white flour. I've found it gives a better result. For tomato sauce, I'm aiming for a fresher, fruitier taste than the slow-cooked rich slop I've used before. I think slightly reduced chopped tomatoes with a little salt and pepper and nothing else should do. Cheese-wise, I note the current trend for random blobs of mascarpone and mozzarella but that's never worked for me. Mixed grated mozzarella, cheddar, monterrey jack and so on has always been my go to. Plus it can be frozen.
Happy to read your own pizza ideas.
