Get the pan down to half the meat's height or less
Broiling without added liquid, or pouring off cooking liquid so it sits at half the meat's height or less before crisping, raised depth of browning to 6-7/10.
Water boils at 212 °F and will not go past it, and a pan with liquid in it is pinned there until the liquid is gone. Browning does not begin until well above that. So while there is braising liquid in the tray, the surface of the pork is being steamed, however hot you set the oven — the energy is going into evaporating the liquid rather than into the meat.
The reassuring half is that the braise never wanted that liquid anyway. Cooks whose pork sat at or below half its height throughout still reported it perfectly tender. You are not trading tenderness for colour; you are pouring off something you did not need.
What to do: tip the pot into a colander over a bowl. Keep the liquid — it is worth reducing into a pour-over, and the fat you skim off it is the frying medium the next step wants.
