Bring 200 g grated coconut and milk to the boil. Remove from the heat and leave to stand for approx. 30 minutes. Soak gelatine in cold water. Pour the grated coconut onto a fine sieve and squeeze out the liquid.
Collect the coconut milk, mix with sugar and lemon juice and warm up. Squeeze the gelatine and dissolve in the coconut milk. Pour the liquid into a shallow bowl and allow to set in the fridge for 3-4 hours.
In the meantime defrost the raspberries and puree them. Pass the raspberry puree through a fine sieve. Stir in icing sugar. Roast the remaining grated coconut in a pan until golden brown and let it cool down. Cut coconut jelly into 16 rhombs and roll in the roasted coconut.
Cut pineapple half into 4 slices and arrange on plates with the coconut jelly. Spread raspberry puree over them. Garnish with lemon balm.
