Debone the chicken thighs (detach them from the bone) and pin them together with the roulade needles, with the skin facing outwards.
Preheat the oven to 150 ° C top / bottom heat.
Put the oil in a roasting pan and briefly fry the chicken legs over a high heat. Take out the legs.
Sweat the diced onion in the roaster while adding the butter. Deglaze everything with whiskey and let it reduce briefly. Then add the BBQ sauce, peach jam, water and Worcestershire sauce and stir well. Add the garlic cloves to the sauce and place the chicken legs on top of the sauce.
Cover the chickens and place them in the oven for 90 minutes with the lid of the roaster or aluminum foil.
Garnish the dish with spring onions.
Classic mashed potatoes and corn vegetables go well with this.
