Step 1

Preheat oven to 180C. Heat half the oil and butter in a large frying pan over medium-high heat, add chicken pieces, skin-side down, and cook, turning occasionally, until golden (3-4 minutes). Meanwhile, heat remaining oil and butter in a flameproof casserole, add mushrooms, leek, garlic and rind and cook, stirring occasionally, until tender (2-3 minutes). Deglaze pan with verjuice, scraping base of pan, stir in mustard, then add stock and cream. Bring to the boil, add chicken pieces, skin-side up, then add herbs and season to taste. Transfer to oven and braise until chicken is cooked through (10-15 minutes). Stir in lemon juice and check seasoning.

Step 2

Meanwhile, for buttered green beans, blanch beans (2-3 minutes), drain, toss in a bowl with remaining ingredients, season to taste and serve hot with braised chicken.
