In 2 tablespoons of cold boiled water, soak the gelatin.
Leave until the gelatin swells.
Cut the fruit into pieces, put it in a saucepan, pour in 150 ml of water and let it simmer until soft, stirring the fruit gently from time to time (7-8 min.).
As soon as the fruit becomes soft, remove from the heat and allow to cool slightly.
Transfer the fruit along with the liquid to a blender bowl and puree.
Add the sugar and cinnamon and mix.
Add the whites.
Beat to a fluffy mass and increase in volume by 2-3 times (beat by putting a bowl of fruit puree in a container with ice water).
Dissolve the swollen gelatin in a water bath, pour it into the protein-fruit puree, and beat it again with a blender.
Spread out the lush fruit mass in cremans or cups, put in the refrigerator for cooling for at least 2.5-3 hours.
