Ingredients
>
1/2 cup sugar
>
Pinch of salt
>
1 small bunch basil
>
1 large seedless watermelon
>
2 cups lemonade
Steps
1
In a small saucepan, combine the sugar, salt, and ¾ cup water. Heat on medium-high until sugar dissolves, stirring occasionally. Remove from heat and add the basil. Let basil stand 30 min.
2
Meanwhile, place the watermelon on a rimmed baking sheet and carefully trim a very thin slice off the bottom rind so it sits flat. Trim top quarter off the watermelon.
3
Push immersion blender into watermelon flesh and slowly begin blending. Blend until all watermelon is liquefied, being careful not to pierce walls or bottom. Strain watermelon purée through fine-mesh strainer and return liquid to empty watermelon.
4
Remove basil from syrup. Stir syrup and lemonade into watermelon. Add a ladle to watermelon and serve punch over ice.
