Puffa Puffa Rice!
Not Rice Crispies. Not Sugar Puffs. Puffa Puffa Rice. I am still gutted that you cannot get it any more, though. There is something similar for sale in the Free-From aisle of Tesco, though, which I think they call Honey Puffed Rice or something similarly generic. Ah, here it is and it is by Kallo.
Hmmmmmmm - maybe I ought to ask hubby to pick some up next time he goes to Tesco. I actually like it dry in a cup/mug. Yes, yes I am weird. Why do you ask? ;-p
