One of the coolest things in summer is to eat the iced watermelon. Don't throw the rest of the watermelon skin, it's a good thing, you can make it delicious.
Wash the watermelon rind and cut off the green skin
Cut the strips, salt the water and pour it off
Add lemon juice and fruit vinegar, mix well and let the refrigerator refrigerate for 3 to 4 hours.
Take out the sesame oil and mix well to eat. (I like to eat spicy, so add chili and minced garlic)
