Thanks both! I've looked on mysupermarket.com and it does show tesco as selling it but when I try to put it in my online shopper it only offers me the ready made stuff.
I'll take a trot down the rice aisle and have a look in person next shopping trip.
Sainsburys definintely sell it, its with the savoury rices though not the pudding rices (why I don't know)!! If you can't find any I will pick some up for you and post it off, no problem.
