What to do with watermelon that you can't eat, throw it in a soymilk machine and make a sweet juice.
Cut the watermelon into small pieces and remove the watermelon seeds. (It can be removed without removing it, but it needs to be filtered later. It is too annoying to wash the filter, so remove it in advance)
After cutting the small pieces, throw them into the soya-bean milk machine. Press the juice button, ok.
Wait five minutes, watermelon juice done. Add a little lemon juice before pouring to make the watermelon juice more fragrant and refreshing. Like sweet, you can add a little bit of sugar, and the watermelon juice will be finished. Pour into the bottle, put it in the refrigerator, and drink it with you.
