First, peel the apples, cut out the core and cut into rings about 2-3 mm thick.
Squeeze lemon, mix lemon juice with 1/2 l water, toss apple rings in this lemon water to keep them bright.
Place apple rings on dish towels and let dry for a few hours. Then dry in the oven on trays or grates for about 4 hours at 50 °C, keeping the oven open with a wooden spoon handle.
The rings are dried when they are still elastic when bent, but no more water droplets come out when pressed.
Press the rings into a jar that has a rubber seal to prevent moisture from getting on the apple rings.
Preparation Tip:
Instead of apple rings, pears or other fruit can also be used and preserved in this way.
