Cut seedless watermelon into managable peices. remove the rind and put into blender. Blend completely until it’s a thin liquid. Put blender containing juice in the refrigerator to chill at least 3 hours. The glass I use for my hand blender is like a tall beer glass. It is very heavy and has a handle - Dollar Store $1. To serve: 6 oz very cold, fresh watermelon juice 1 oz chilled vodka (or maybe 2!) Maybe a squeeze of lime I'm taking it to a neighbor's party today. Let me know if you like it. Cheers!
