You can buy it in asda, tescos , sainsburys, and i bought some in morrisons yesterday , its in the chillers with all the cheeses, usually near the more unusual cheeses , such as danish blue, mozarella etc
if you cant find it, ask a shop assistant, but they will sell it, most of the big supermarkets do
It's a really low fat soft cheese type thing. free on both days. It's used in recipes like cheesecake, macaroni cheese etc tings like that! Not too bad as a syn free dip for carrot sticks.
hope that helps!
