Can't we just grind the watermelon juice in a blender? I don't know if there's a tip, but there's a way to make it more delicious food^^
First, cut the watermelon. One glass is about 200-250g. A large watermelon removes all the seeds.

Place watermelon ice sugar in blender. Isn't water supposed to go in the juice? So I used to add water and change it.. It was really bad. Here's a tip! Watermelon is a moist fruit, so you don't need to add water. It's one of the tips to cool down with ice, but the more ice you put in, the more slushy it is. (A moderate amount of ice!)!! It's better to put it in, right? Another tip is that no matter how sweet the watermelon is.. It doesn't taste good if you just add watermelon and grind it. It depends on the sugar content of the watermelon, but add sugar to suit your taste and grind together. One tablespoon was right for each glass. (No honey or sugar syrup!)!! It tastes better if you add sugar.) Also, when you add watermelon, the sugar content at the center and end of the watermelon is different, so it's better to mix it and grind it, right? ^^

Grind the ice and watermelon finely with a blender.

You thought it would end here, right? It's cool and delicious just by eating the watermelon.. It tastes like something's missing by 10%. The reason is??? It's because there's no chewing taste!! Here's the last tip to make watermelon juice 100% delicious. Cut the seeded watermelon into small pieces.

If you mix the chopped watermelon with the watermelon juice, the watermelon juice is more delicious than the cafe ^^
