Do u want to sell your 40 inch. lol Sorry.
Man, I'm no expert but I always get great ribs.
1 - The night before, I pull the membrane;
2 - rub mustard over the spare ribs;
3 - Use
Jeff's rub (I also add 1 TBS of Cumin);
4 - Wrap in saran wrap;
5 - Next morning, preheat my MES 30 to 275 and 8 hrs;
6 - I get my MNPS loaded with a mixture of Hickory and Apple or Cherry;
7 - I keep my torch on the MNPS hole for 40 seconds and then let it burn for about 15 minutes or so adn then will blow out the fire. At this point the MNPS is smooking good;
8 - Once the smoker gets to 275, I'll open the door, throw in my rack and sprinkle some more rub on top;
9 - Insert teh MNPS into the bottom and then open the side wood tray and internal ash tray;
10 - I then turn the temperature down to 240 and verify that the vent is wide open;
11 - I don't do 3-2-1, I don't like the taste of the ribs. But I won't open the door until 4 hours later. At that point, I open just to spritz some apple juice on the ribs;
12 - For me, the entire cook time is 6 - 7 hours. By then, I have a perfect rack of ribs.
As people have told me, don't over think it. It just becomes a natural process.
Good luck!
