Wash the apples, peel them, and cut into cubes
Pour water over the apples, place on medium heat and stew until soft, about 10-15 minutes
Blend the apples with a blender, add gelatin, and mix well. Let cool to room temperature
Beat with a mixer on high power for about 20 minutes. Note: the mixture may seem unchanged at first, but around the 20th minute it will start to change - the mass will increase 2-3 times in volume and turn white
Transfer the mixture into a parchment-lined form and cover with plastic wrap
Refrigerate for 2-3 hours until the pastila is ready
