Well I buy both regularly in my weekly groceries, down under they are completely different, in looks and taste. I have one of each in fridge and freezer right now.

A crumpet is an airy type product with a hard base, they are 99 per cent fat free, and i just pop them in the toaster, with a bit of jam on them, yummy, probably my lunch today.

Crumpets can be toasted too of course and used for other things, like mini pizzas, they are much more solid and come in different flavours, like spice and fruit,cheese etc,they are 98 per cent fat free,they do have similar ingredients in them, but they taste completely different.

They are both delicious and fit in with my WW very nicely.
