Hello-- I have a Weber Spirit E-210 and want to grill ribs for the first time. I bought spare ribs from Publix, am going to trim them St Louis style and use a rub and sauce. Looking around online I have found many different lengths- from 45 minutes to 6 hours. Any recommendations on temp/time using a grill like mine and spare ribs? Having a friendly competition for the holiday tomorrow and I am new to this; any help is appreciated!
