To make the poached pears, place all the ingredients except the pears into a small saucepan. Half fill the pan with water and bring to the boil. Simmer for 10 minutes to infuse then drop in pears, cover and gently poach for about 20-30 minutes until soft. Turn off the heat and set aside. To make the chocolate sauce, tip the chocolate drops and cream into a small pan and heat together until you have a sauce, stirring constantly. Meanwhile, prepare the chocolate chip crumbles. Preheat the oven to 170`c and grease small individual rings and place onto a lined baking sheet. Cream the margarine, sugar and vanilla essence together until soft and fluffy. Mix in the flour until all combined. Pop half of the mixture into the base of the rings and sprinkle over 2 spoons of chocolate chips . Cover with the remaining crumble, sprinkle over the chopped hazelnuts and remaining chocolate chips. Bake in the oven for 20-25 minutes, or until the top is golden brown. Leave to cool down in the ring for 5 minutes before serving dusted with icing sugar, along with the poached pears and chocolate sauce.
