1 kg of apples https://greenelly.com/ are peeled, cored, and cut into slices.
Dilute soda in clean cold water at the rate of 1 tablespoon per liter of water. Place apples in the solution, apply a lid or plate so that they do not float and leave in the solution for 6-9 hours.
Pour 300 ml of water into a saucepan with a thick bottom, add 1 kg of sugar, put on fire and dissolve, stirring occasionally. Pour apples into boiling syrup, after washing them well.
