Using Tom Kha soup as a poaching liquid

Wanted to poach some snapper yesterday and had a hankering for some Thai flavor. One of my pantry staples is tom kha soup base, and I had a little coconut cream left over from making that Whiskey Crab Bisque. So I chopped up some red onion, some carrot, some boiling potatoes hanging around in the fridge (still trying to clean out some before vacation) and a sweet potato. Sauteed the veggies, then added a couple of tablespoons of tom kha paste, a cup of coconut cream, a can of chicken broth, and a can of water as well as the zest from a lime. Simmered about 15 minutes until the sweet potato was about done. Turned the heat to very low and laid the fish fillets on top, covered and let them sit about 15 minutes. Served with rice, it was very nice.
