Ingredients
>
6 cups cold water, divided
>
3/4 cup sugar
>
1 large red grapefruit
>
3- 4 lemons

2 (6 oz) containers fresh raspberries
Steps
1
In a medium pot, combine 2 cups water and sugar. Heat on high, until sugar dissolves, stirring occasionally. Remove from heat and let cool.
2
Meanwhile, squeeze the grapefruit to get ¾ cup juice. Squeeze the lemons to get 1 cup juice. Squeeze the limes to get ¼ cup juice. Add all juices to a pitcher.
3
In a blender, purée the raspberries until smooth. Strain through a fine-mesh sieve into the pitcher with citrus juices, pushing on solids to extract all the juice. Discard solids.
4
To pitcher with citrus juices, add sugar syrup and remaining 4 cups cold water. Stir to combine. Refrigerate until cold. Serve over ice. Garnish with additional lemons, limes, or raspberries, if desired.
