Comment on Super Crispy-Skinned Slow-Roasted Pork Shoulder by Beth.
This is a little late, I realize…but I gave found that the rack is unnecessary. We did 2 of these, side by side, one on a rack and one just in the roasting pan. The one without the arch was actually better, as the pork cooked in its own fat, making sort of a confit after 10 hours. Spectacular.
