I ate out at a restaurant recently and had a delicious soup which they called tom yum. It had no soy sauce or fish sauce in it (I checked), they said the broth was basically chicken soup mix, water, and coconut milk. Plus I'm sure other stuff. It was very creamy and thick and delicious and out of this world, and I'd like to recreate something similar, only with real chicken broth, not soup mix. Any ideas for a recipe? I can't have anything with fish or fish sauce in it, because I keep kosher, and all the recipes I've seen called for those. I dont have lemon grass, and I dont have a way to get keffir lime leaves, but I do have fresh lemon leaves if I can use them in their place.
