Well, what can I say! Soz if people don't like this but I thought and still think it's the dogs bollocks! Strawberry with creamy cream cheese and a slight yoghurty tang. Does we need at least as weeks steep, possibly two.
Taste is subjective ( yawn... There I had to say it :-) ) but it really is. Millions of Americans would probably think I was frigging weird if I said root beer floats tasted of sick, germalene and arse but they do!
At worst it it is £4 wasted but again, hang in there a week at least. And yes, a frothy-ness after a vigorous shake isn't uncommon at all. It will settle out.
