Tips for keeping lemons fresh
1, lemon peel is rough. The fresh lemons bought should be cleaned with a small toothbrush. When you brush lemon, you can dip a little salt in it, which can easily brush off impurities and dirt on the lemon peel.
2. Freeze the cleaned lemon in the refrigerator for 2-3 hours. Lemon juice can be solidified during freezing, and it is not easy to be lost in subsequent operations.
3. Take out the frozen lemon and cut it into thin slices. Note that the thinner the lemon slices, the better, which is more convenient to use. Frozen lemons are easy to cut and not easy to spill.
4. Slice the lemon slices in a fresh-keeping bag. When coding, pay attention to spreading the lemon slices as flat as possible, which is convenient for taking and eating later.
5. The juice of frozen lemon slices will not be lost, and it looks like lemon-shaped ice cubes. When it's hot, it's very refreshing to soak such frozen lemon slices in water.
6. It should be noted that when taking frozen lemon slices, just take a few slices. Don't thaw the whole packet of lemon slices at once. Lemon slices that have been thawed repeatedly tend to be soft and rotten.
