Cut each apple into 4 pieces, removing the seed box, but be sure to keep the skin.
Place the slices cut side down on a baking sheet.
Preheat the oven to 180°C, place the apples in, and bake for about 25 minutes. This will result in a puréed flesh and a slightly darkened skin.
Place the baked apples in a deep container and blend until smooth using an immersion blender.
Collect the puree in cheesecloth and place it in a sieve placed over a deep bowl. Then refrigerate for 8–9 hours to allow excess moisture to drain.
Pass the thick mass, freed from moisture, through a sieve to get rid of the pulp.
Place the applesauce in a blender and blend until it becomes light in color.
Pour the egg white into the mixture and continue whisking. The mixture should become even lighter in color and double or triple in volume.
Add sugar to the already fluffy mixture. Add 1 tablespoon at a time to allow the sugar to dissolve.
To glue the layers of pastila together, place 3–4 tablespoons of apple mixture in an airtight container and refrigerate.
Place the remaining mixture on a parchment-lined baking sheet, spread it into an even layer 2 cm thick and place in the oven.
Dry the pastila at a temperature of 70–80 °C for 4–5 hours.
When sweet drops appear on the layer, continue drying with the oven door open.
The pastila is ready when the surface is dry and soft, and there are no dents when pressed. After this, remove it from the oven and let it cool.
Separate the pastila from the parchment and cut it into three equal parts with a wet knife.
Remove the apple mixture from the refrigerator and layer it between the layers.
Place the assembled mixture in an oven preheated to 80°C and leave for 2–3 hours.

So should I use the yolk or the white?
