Just wanted to say this is a great site. I am new to smoking meat and have learned alot from this site so far. With all of the advice that is given on this site, I feel that I am starting with an advantage!! I do have a question which should show my inexperience though. If I am following a recipe for a rub or bbq sauce and I want to make more of it or less of it than the recipe calls for, can I just half or double the ingrediants without changing the taste of it, or do I have to preform some sort of NASA style mathematical equation?
