I use the Blair essence (sparingly) in certain recipes where I don’t want to add any flavor from the sauce but want to add a little heat. I also have a low serial number Blair 2am that sit’s on the shelf for conversation. As you noted it doesn’t have any flavor and should NEVER NEVER NEVER be used anywhere close to straight. It will do physical damage to you. I always use gloves when handling my open bottle.
I'm really curious, I'll probably wind up experimenting a good bit, but I'm trying to get a feel on what kind of flavors they are...since all the names just have variations of the word death.
