I followed this for my second smoke in the SI3.
2 racks of ribs with Memphis Dust rub and 2.5 oz of mesquite chunks.
170 for 30 mins then 235 for 4.5 hours.
I did the toothpick test, wrapped in foil and lowered the temp to 130 until dinner time. They were really moist with a nice bark and great flavor.
Thanks for the recipe and timeline!
