Zhen Zhen Porridge, Maxwell Food Centre
For some reason, I got the fish version today rather than pork variety that they are known for, but nonetheless, these guys at stall #54 do have a pretty good porridge, where rice has been stewed so long that they are not even in grains anymore, but rather one thick sludge. I was a bit disappointed to find that part of the flavor of this porridge depended on those little brown salted vegetables on top (and I was surprised to see how crudely the scallions were cut here), but those didn't really matter in the end, as it was still pretty darned tasty.
Be prepared for the Porridge Nazi here though; the grumpy lady shouted at me today and didn't even make eye contact throughout the entire transaction. I guess it was a rather amusing change from the guy down at Ho Kee.
