Don't worry. I am not becoming a food blogger. However there was some confusion over a (very pleasant) lunch in Shanghai today as to what exactly this - the dessert included in our set meal - was. There were excellent Chinese speakers there, but the giggling waitress was rather testing their vocabulary with an account of it being made (so they understood) from the generative organs of a frog. It actually looks more like frogspawn, which may well have been what she meant.
I was not up for trying it myself but it smelled quite pleasant. The idea was to pour syrup and milk on it and then scrape it, along with the fruit, onto a spoon and eat it. We were told it's good for longevity (though it doesn't seem to have helped its original owners in that respect).
Can any knowledgeable reader tell me what my braver friends were really eating?
