Melt the butter in a large frying pan and add the apples and pears, skin side down. Cook until tender, turning the fruit over to brown evenly. Remove from the pan and keep warm. Add the cloves, cinnamon and butterscotch sauce and warm the sauce. Place one apple and pear quarter on each plate and drizzle over the butterscotch. Serve with vanilla ice cream or clotted cream and shortbread biscuits.
