Remove from heat and add mustard, molasses, honey and lime juice. Stir to mix well; remove half of mixture and reserve. In remaining half, place chicken and marinate in refrigerator at least l hour or overnight. In large frypan, place oil over medium heat. Add chicken and cook, turning once, about 10 minutes or until fork can be inserted with ease. Remove chicken from frypan and keep warm. To frypan, add chicken stock and cook to reduce by two-thirds. Add reserved marinade and butter; simmer, stirring, until butter melts. Pour over chicken.
