Our second run at pulled pork was wildly successful. We used a different rub (hickory garlic, very tasty) but I think the big differences were in cooking technique. First off, I foiled the pork butt at around 150 degrees. This is where you wrap the thing in foil with a half a cup of water or apple juice in it. As the chart below shows, this more or less eliminated the stall while the moisture from the meat evaporates.
Third, I let it sit in the cooler for a full hour, not just 30 minutes, so the moisture distributed better.
End result was awesome.
