2. When boiling hawthorn water, you need to prepare fresh hawthorn and appropriate amount of sugar. In addition, you need to prepare enough water and proper amount of edible salt. Dilute the prepared edible salt with clear water to make brackish water, and soak fresh hawthorn in brackish water.

3. Take out the soaked hawthorn, cut it with a fruit knife to remove the seeds and stalks inside, cut the obtained pulp into blocks, and rinse it with clear water. Put the prepared sugar into the pot together, add enough water and heat it with high fire. Cook slowly for about half an hour, and turn off the heat when the hawthorn pulp in the pot is cooked to a soft and rotten state.

Don't take it out after turning off the fire. Put the boiled hawthorn water in the pot for one night, and you can take out the sweet and sour hawthorn water the next day. The boiled hawthorn water will taste more attractive after refrigeration. In addition, when people cook hawthorn water at home, they can also add a proper amount of lemon juice, which will make the boiled hawthorn water have a faint lemon fragrance and prevent the boiled hawthorn water from deteriorating during storage.
