I got mine in my local Chinese supermarket Wai Yee Hong (near to Ikea in Bristol) after the lovely lady running the Twitter account recommended them to me :)
They take a bit of getting used to! They've got a squishy outer shell made from glutinous rice, with the 'ice-cream' inside. I've got the coconut flavour and I'm truly addicted. I'll be going back to get the chocolate flavour very soon!
Allergy advice says: contains coconut (tree nut).
