Aeroplane Jelly
In Australia, jelly=Jell-O, and apparently Aeroplane Jelly is an Australian icon. When I saw it on sale at the grocery store recently, I bought the most random flavour on an impulse. Rather than get a regular fruit flavour, I got Wobble, the dairy version, which had a hula-hooping cow on the box. It isn't chocolate pudding or mousse, it really is firm like Jell-O.
I can report that it was...not bad. One box for $0.99 made 4 servings, which kept me in dessert for a few days. Matthew didn't care for it.
