I did a little experimenting in the kitchen and came up with this drink for kids or adults. (Adults version with a splash of Vodka)
2 cups of frozen berry medley
1 cup of squeezed lemon juice
1 cup of Sugar
8 cups of Water
In a small saucepan put 2 cups of frozen berry medley, 1 cup of lemon juice, 1 cup of sugar, 1 cup of water. Let it simmer until the sugar is melted.
Put it into a blender, until it’s completely smooth. You can strain it if you don’t like the berry seeds. It didn’t bother me, so I left it. Add the rest of the water and serve it on ice. For adults, you can add a splash of Vodka.
P.S. You can add more sugar if you desire it on the sweeter side.
