Yin Yang

Yin Yang has often been use to name food of mixture but it's probably more meaning full if they were opposites ie the 'black and white' drink although it's more often use for coffee and tea mix or mix noodles.

I had the luxury of enjoying the Yin Yang crab because the restaurant had insufficient mud crabs:
Mud Crab and Snow Flower Crab in Ginger Butter Black Pepper Sauce on Egg Noodles

Certainly not the kind of dinner that I'll be having on a date but the dish was lovely because you can appreciate the difference in the crabs. The Mud had a stronger sweet flavour but the Snow Flower although more subtle in flavours had a more delicate texture but boy do you have to work to savour these beauties. I've never appreciated crabs more.
