During the summer, you can normally get ribs on sale fairly regular, when you see a good price...buy a bunch...freeze them...and start experimenting...one at a time...you will get oriented quickly as to what you do and don't like....You can cut a rack of ribs in 2 and try 2 different methods...it is your grill...be the man, see what works and what don't...
even a well tried recipe on here , may need practice at your grill, your location...and hey....the fun is in the practice....I just tried the 3-2-1 here at my house...my grill for the first time..turned out great, but I will make a few modifications for the next run...mainly to my choice of rub, not the method...I have learned that I enjoy cooking one day....and eating the next several...so it takes a few days to figure what I may want to change,.
