1, sweet and sour plum. Ingredients: plums, sugar and salt. Practice: After fresh plums are washed, cut a few times on them with a knife. Be careful not to scratch them too lightly. Pour some water into the pot. When the water boils, pour the cut plums into the pot. Stir with a spatula until the color of plums changes. Be careful not to have water. Add the right amount of salt and a little sugar, and you can eat it directly.

2. Plum juice. Because of varieties and other reasons, the taste of plums is still very sour. This kind of direct eating tastes bad, and it can also be juiced. If it is mixed with other sweet foods such as honey or rock sugar, it can improve the taste without affecting the nutritional value.

3. plum jam. Too sour can also make plums into jam, eat a little every day, scoop bread, mix yogurt or drink with water, which will increase appetite and supplement vitamins. Practice: Wash the plums for later use. Peel with a knife. Boil peeled plums in a pot and add some water. Just cook it over medium heat. 1 hour or so, the pulp is completely boiled and the stone is exposed. Pick up the stone and throw it away. Continue to cook until the water thickens. Cool it a little, put it in a clean water-free and oil-free glass bottle while it is hot, and store it upside down, so that it can play a bactericidal role when it is put in for the first time and promote the better preservation of jam. Note: Don't stir all the way, or you will stir all the time or paste the pot. The glass bottle containing jam must be clean, free of water and oil.
