Hi Donnie,
I've recently used the WW S&S Sauce for the very first time, and the 350g jar - as far as I know, the only one they do - is only 7.5 syns for the WHOLE jar, so you may be 'overcharging' yourself there!
We thought it was delicious with its peppers, baby corn and pineapple. We had it with a stir fry though, but at £1 a jar down here, we'll keep a jar to hand. I'm off now to see how much of a faff making it from scratch would be!!! Thanks all.
