I have some great ribs going 321 method however dinners has been pushed back so they will finish 2 hours early how shall I hold them.
After the 2 hours of cooking while wrapped, just pull them from the smoker and let them rest. Keep them wrapped tight until you're getting ready to serve. Then, about 30 mins before you're ready to serve, unwrap them, glaze them and put them on the grill to caramelize the glaze.
They should keep their juiciness and not be overcooked.
