I was first introduced to this summer treat by L and Sunggyu on Sesame Player.
Cut water melon in half and take out all the insides.
Put the insides in a container and add milk and cider to taste.
Now for a REAL recipe:
수박화채 is often translated as 'watermelon punch' and is normally eaten in the summer. I attached a video, but here's a transcription:
1/2 cup water1/2 cup sugarpot
2. Don't let the water boil! Just let the sugar melt to create a syrup then transfer it to a cool bowl.

sparkling water. *some people add milk as well to make it creamier, but its not necessary)
