I've been considering moving from liquid to powder for a wee while now, and have just been trailing the Tesco Naturally Powered powder which I have liked so far. However, I don't do my main shop in Tesco so unlikely to use this much in the future. I personally haven't had any problems with it gunking up and not dissolving properly in the drawer either, which seems to be a common complaint from some.
So which powders do you recommend? (We shop in Sainsbos if their own brand was recommended)
