thank you so much for answering my question about covering pork roast with alum. foil. I will cook the roast just as you said. I can hardly wait. TONYA

The crust that develops as you cook it is probably the best part of the roast, so I don't think I would. There's enough fat in the roast to keep it from drying out.

OK, yeah, this is as luscious as everyone says. I was scared about putting it into an oven uncovered for that long, but took a leap - it was phenomenal. Presumably, you could switch out the spice rub infinitely.

are there any thoughts as to making this with a smaller cut? three pounds would be excessive for my two person household. could I still do this? or is not worth it to make with a three pound cut?

I wonder how this would do in a dry crockpot.

This recipe produced the most delicious pork roast I've ever eaten! I put the rub on the night before and set it in the roasting pan so it'd be ready to pop into the oven when I left in the morning before work. When I got home, it was perfectly cooked! Moist and flavorful! I made a quick pan sauce with the juices, but it really didn't need it. It was simply gilding the proverbial lily. We'll definitely be making this again!
