Lightly clean pan with paper towels.
Heat pan over medium heat and add 1 1/2 teaspoons butter to pan; swirl until butter melts.

Return chicken and any juices to pan; turn to coat with sauce.
Top chicken with lemon mixture. Sprinkle with parsley.
Notes
adapted from The Joy of Cooking, 1964 editionWatch the lemon mixture closely so as to only char the rinds. You're not trying to burn the inside fruit, if you do so the sauce will have a burnt taste.
