If you read the statement above from SW it doesn't say that using instant mash as a pizza base means it must be synned, it only said when used as a sauce thickener. I have contacted SW with my recipe and will wait for their reply!
At approx 25g per pizza that's less than I would mix & eat as a portion of mash & the only difference is that I cook & brown the mix, I don't see that you have to syn potatoes when used as chips because you have cooked them in a oven.......
It has always been a grey area, both my consultants have said it's free, others say it's not! Lets see if I get a reply..........
