Chicken Breasts with Chive and Mustard Sauce

I made this epicurious.com recipe for Chicken Breasts with Chive and Mustard Sauce a couple of nights ago, as chicken breasts were on sale at Safeway. We all liked it very much – even Mika (who was mortified she liked a sauce that had mustard and alcohol in it). Camila ate the chicken without the sauce, which is typical.
The one problem with the recipe is that it was very, very liquid – even though I only used 1 cup of chicken broth. Next time I’ll use 1/2 a cup and I may add some cornstarch to thicken it. The flavor, however, was wonderful.
