Take the apples (2 large ones) and cut them into halves. Peel and remove the core. Then divide by 2 more, getting quarters. We send it to the oven with a temperature of 160 degrees for 1 hour.
In principle, you can do it in the microwave (15 minutes), but then the unnecessary liquid will not evaporate and marshmallows may eventually turn out crumbly and not freeze! Therefore, I strongly recommend baking apples for the right marshmallow!!!
