Jambalaya help. Rice not done

Add a little water then put it in the oven?

Roll or turn it with a little liquid, not much. And add a bit of heat with a tight lid for a few minutes(5 to 10), and it'll likely pop.

Do what Otis said

Put it in a roasting pan, seal the top tight with aluminum foil (where very little if any steam will escape) and stick it in your oven on the middle rack at 350 for about 20 minutes before you check it. If it's still not done, repeat.

I've done this before. Getting a good seal steams the hell out of it without adding more (and possibly to much)liquid.

Putting it in the oven takes it off of the direct heat, and makes it less likely to burn or scorch (actually pretty hard to burn it this way).
