1. First, wash the apples. You need to dry the water with the peel. Next, remove the handle of the apple, then cut the apple and remove the core inside. The core is taken out because the core contains cyanide, which accumulates in the body in large quantities, causing harm to the body and coma in severe cases, so the core should be taken out.

2. Cut the apple with the core removed into 2 cm pieces or slices;

3. Prepare an oil-free and water-free container. Sprinkle a layer of white sugar on the flat bottom first, then put apples, a layer of sugar and a layer of apples, and so on until the apples are finished, but the sugar must be on it and covered. The top layer of sugar should completely cover the apple and then put it in a cool place;

When the apple begins to ferment, the sugar will slowly melt and the sugar water will leak out. You need to open the bottle halfway and get some air. If it's too much trouble, you can buy a special container for putting enzymes.

5. The fermentation time of apple enzyme is 2 to 3 months. After the fermentation, filter out the liquid, which is the apple enzyme, and put it in a clean glass bottle, so that the apple enzyme is ready.
