I got a couple of packets quite a while ago - when Morrisons were doing a BOGOF on them.
They aren't very good, it was mainly the smell which put me off. I'd have assumed that for Ainsley Harriot to put his name on them they'd probably be okay-ish.
However, as Mr Caxton suggests, they probably formulated them first then gave Ainsley a big fat cheque to use his name.
