This dish turned out so much better than I expected. The hormone-free chicken was pan seared with just a bit of salt and pepper until nicely browned and crispy. Meanwhile the polenta was prepared by sweating out onions and garlic in a pan. Four cups of chicken stock went into that and a cup of coarse corn meal was whisked in once it reached the boiling point. This was cooked with frequent stirring for about 40 minutes until it was smooth and thick. The sauce was made in the pan that was used for the chicken. After the chicken was browned and set aside, chopped garlic and onions were added to the pan followed a minute later by sliced mushrooms. These were sautéd until softened and the pan, with all those wonderful chicken drippings, was deglazed with a half cup or so of white wine. The juice of one lemon was added. The sauce was reduced for a few minutes and then mounted with a pat of butter to give it a rich texture. The chicken was plated on top of a bed of the polenta and the sauce was spooned over it.
