Bubble tea and Dubai chocolate seem to be the in thing at the moment, or at least it is in the UK. Bubble tea has been around much longer in places like Hong Kong.
Pistachio flavoured everything is very last year, but I prefer pistachio in their natural form.
Not bothered about salted caramel.
Going back to the late 90s I realise now that goat's cheese is rank, but I still like sundried tomato paste in things like lasagne or bolognese sauce.
