Chicken with Black-Pepper Maple Sauce

I made this epicurious.com recipe for Chicken with Black-Pepper Maple Sauce for dinner tonight. It was awesome. Or rather, the sauce was awesome. The chicken was OK, the skin was great, of course, but not much flavor penetrated into the flesh. But the sauce was incredible, even though I forgot to add the two tablespoons of butter needed to finish the sauce. As Mike put it “I’d eat anything dipped in that sauce”.
I followed the recipe pretty closely but I used a 5.5 lb chicken instead of a 3-3.5 lb one. I’m sorry, but it’s unrealistic to feed a family of 4 (and we were one more tonight) with just 3.5 lbs of meat. The 5.5 pounder fed the five of us well, and we have a couple of leftover pieces. The problem, however, is that it took longer for the chicken to cook (about half an hour longer), and the breasts overcooked a bit. Next time I’d use chicken pieces instead of a whole chicken, and I’d remove each part when it is ready. I increased the sauce ingredients by one-half to accommodate the larger chicken, but if I was going to make it again, I’d at least double the sauce recipe. It’s that good.
I served the chicken with couscous and green beans. The sauce went incredibly well with the couscous and I’d recommend the pairing.
I should note that I only used about 1/2 Tbsp of peppercorns, rather than the required 1 1/2 Tbsp. As it was, the sauce wasn’t in the least spicy, so next time I might increase the amount.
