I can use or not use, thats the cool thing about being able too choose for yourselves. Folks that I sometimes cater for usually have an idea of what they want so I cook to customer specs. I don't think I have ever told anyone, this is how I do it, take it or leave. I am a chef and pit master and enjoy cooking to the specs. of clients, sometimes its even challenging.
I mainly choose to leave it alone for my choice but sometimes I use a little too.
