Have to agree with Lizzie. I picked some up from Asda's and tried a slice and have to say, it wasn't too great. Then again, neither was the other cheese that my other half got at the same time which was also made by the same farm.
Trouble is I'm too used to cathedral city!
I've got a block of the weight watchers cheese which is 10% fat and they also do a grated version which isn't too bad. If I have cheese I just use that as my 100 cal high fat treat. I don't have a treat every day so the cheese probably uses 2 of those.
However, back to the RC cheese. It's apparently available in Asda or Morrisons so if you can't see it with the other cheese then I'd ask to check and see if they stock it.
