1 or more whole chickens
2 tablespoons sour cream
2 tablespoons dijon mustard
Preheat oven to 400 degrees. Wash, dry and salt the chicken and put in a pyrex baking dish. Squeeze the juice of 1/2 a lemon inside the chicken cavity. Add sage leaves (the more the better), sour cream and mustard inside the chicken. Peel potatoes and nestle in baking dish with the chicken. Sprinkle rosemary and drizzle olive oil on chicken and potatoes. Bake at 400 degrees for 1 1/2 hours. Serve it with love.
