Wash, peel, quarter, core and cut apples into small pieces. Put them into a large pot with sugar, ground cinnamon, cinnamon sticks, nutmeg and 400-500 ml water. Bring to the boil, cover and simmer for about 30 minutes. Stir in between
In the meantime, wash glasses with twist-off lids hot and let them drip off upside down on a clean tea towel. Remove the cinnamon sticks from the apple compote and mash the mixture with a potato masher to a fine pulp (approx. 1.6 litres of thin apple puree). Pour hot apple sauce into the clean glasses to about 1 cm below the rim and close them tightly. Place the glasses on the lid for about 5 minutes. Then turn them over again and let them cool down. Apple sauce lasts at least 3-4 weeks.
