Did you not allow your soil to sit for a while, or did you allow it to sit and then just added the bone meal at the last minute? If it's the later, you should be fine. "Cooking" your mix in simple terms means allowing the microbes present in your soil (which came from whatever source of compost you used) time to break down and store in bioavailable form the organic amendments that you added. If you didn't allow your mix to sit at all you might run in to some issues as some of the higher N sources can be hot while being broken down, but something like bone meal would be fine. It just won't be available to the plants until the microbes go to work on it.
