I started with raw, unpeeled shrimp, onions, carrots, celery, mushrooms, garlic cloves, and tomatoes. I let that boil for about an hour and then added salt, pepper, cumin, crushed red pepper, and parsley. Boiled that for another hour or two-I didn't put on a timer. Once strained, I was surprised by how great it was. That's the first time I had made broth from scratch and I just put in whatever I liked, so I was happy it turned out. I like spicy, but I'll leave the crushed red pepper out during the post-op healing time. I've got another week on the pre-op liquid diet to enjoy it.
