My dad NEVER TASTES ANY MEMBER THE CARROT FAMILY WITHOUT KNOWING EXACTLY WHAT IT IS.
I once horrified a collegue when we were doing some plant ID, he had found a plant which was a member of the carrot family and was struggling to identify it as it didn't exactly match any of the descriptions in his books.
I had a quick look, took a piece and stuck it in my mouth. I was 95% sure it was just cow parsley, but the look on his face was sheer horror and he kept expecting me to drop dead any moment. I could easily have been 5% wrong.
I now always think of that whenever I'm about to try something I'm not sure about.
Glad you surrvived.
