In a large, heavy saucepan, cook the bacon over medium-high heat until crisp and the fat is rendered, 4 to 5 minutes. Remove and drain on paper towels. Drain off all but 1 tablespoon of the fat.
Season the chicken on both sides with Essence. Dredge in the flour to coat lightly, shaking to remove any excess. Add the chicken to the fat in the pan and cook over medium-high heat until golden brown on both sides and nearly cooked through, about 4 minutes per side. Remove and cover to keep warm. Add the onions and cook, stirring, for 3 minutes. Add the Calvados and cook, stirring, to deglaze the pan. Simmer until reduced by half. Add the cider, bring to a boil and cook until reduced by half. Add the apples and cook, stirring, until tender, about 2 minutes. Add the cream and simmer until reduced by half. Reduce the heat to medium-low and add the butter, several pieces at a time, and cook, stirring, until each is incorporated. Stir in the thyme. Return the chicken and any accumulated juices to the pan and cook until the chicken is heated through and cooked all the way, turning, 1 to 2 minutes.
Remove from the heat and divide the chicken and sauce among 4 plates. Garnish each serving with the bacon and fresh chives and serve.
