I a rookie at all this too, and have not done the thighs yet. Having said that, I would take that liquid, which should have come from the thighs, add it to the fond in the pan you used to sear...and add some vermouth, fresh sage, and a little bit of low sodium stock. Reduce by half, and you will have a decent pan sauce.
And i have not done yet, but think someone on here said to absolutely re-season after the drying and before the sear.
BTW, has anyone used a hair dryer to try and get the meat as absolutely dry as possible?
