Prepare everything you need. Soak the gelatin in 50 ml of water in advance and leave it to swell for the time indicated on the package.
Wash the raspberries and put them in a pan. Pour in the remaining water.
500 g raspberries, 150 ml water
Put on the stove and wait until foam starts to appear. Do not bring to a boil, just heat it up.
Strain the raspberries through a fine sieve, discard the seeds. In warm raspberry puree, add sugar and stir until dissolved. If the berries are sweet, you can use less sugar.
⅔ cup sugar
Heat the swollen gelatin in a water bath, but do not boil it, otherwise it will lose its properties. If you see that not all crystals have dissolved, strain through a sieve. Add to the raspberries.
20 g gelatin
Mix everything and pour into a mold lined with food wrap. The layer should not be too thick, ideally 1.5-2 centimeters. Put in the refrigerator for 5-6 hours, or better overnight, to set.
Turn the marmalade onto a plate, cut into individual pieces, you can roll them in sugar on all sides.
The raspberry marmalade is ready. It is better to store it in the refrigerator until serving.
