Bring cream and 75 g sugar to the boil in a saucepan. Stir in vanilla pulp, let cream boil down for about 10 minutes. Soak gelatine in cold water. Remove cream from the stove and let it cool down for about 10 minutes. Dissolve gelatine in it. Stir in orange peel. Pour into an ovenproof dish (approx. 21 x 20 cm) and chill for at least 2 hours.
Put honey and Grand Marnier in a bowl and mix. Peel oranges so that the white skin is completely removed. Cut oranges into slices and add to the sauce. Hold the casserole dish briefly in hot water and turn over onto a board. Cut out 4 hearts (8 x 8 cm) with a cookie cutter. Arrange the hearts with the orange slices on plates. Decorate as you like with dusted mint leaves
