Roughly chop the chocolate. Bring the cream to the boil, remove from the heat and melt the chocolate in it. Wash and quarter the pears, remove the core. Sprinkle pears with lemon juice. Whisk the egg.
Cut quarters into 3-4 columns each. Turn slices first in flour, then egg and then in grated coconut. Heat the oil in a large pan and fry the pear slices over medium heat until golden brown, turning them over.
Arrange immediately, dust with icing sugar and serve with the chocolate sauce. Decorate with lemon balm.
