Halve the melon (use one half for other purposes) and remove the seeds with a spoon. Cut out 4 balls with a ball cutter. Remove the rest of the pulp, place in a bowl, add brandy and puree.
Divide into 4 small plates. Wash the figs, dab dry and cut in half. Place on the sauce pan. Whip cream and sugar until semi-stiff, stir in lemon juice and zest. Spread lemon cream over the figs and serve decorated with lemon balm and melon ball.
