Ingredients: rock sugar, white vinegar, olives.

1. Wash olives and shower with boiling water.

2, rock sugar and vinegar are cooked together (without adding water). If you like sweet, add more rock sugar. If you like acid, add less.

3. When the rock sugar is about to melt, pour in olives and boil. If you like soft olives, cook them for a while. I like crunchy. Turn off the heat when it boils. If you can keep olives from being polluted, you can soak olives in sugar and vinegar instead of boiling them.

4, find a sealed jar, put it away, let it cool, and you can enjoy it slowly.
