I let the picnic smoke sans mop for about an hour then baste it every 1 to 1 1/2 hours with Fergy's shotgun mop. Recipe follows.
The main thing is at least 50% oil! Also, I feel that you need to add extra Kick if you want it spicier because the oil seems to block some penetration of the spice. Also, I strongly believe that to get better smoke penetration (i. E. start with lower heat and build up) is a necessity if you want a strong smoke flavor. The oil seems to also block smoke penetration. I have had great success with oil and the start low method. But then, I like to belch on Wed. And blow smoke rings from Q on Sat.!!!
