Raspberry Shake

Wash and pick over the raspberries; set aside a few especially nice berries for later garnish.

Place the remaining raspberries together with the raspberry juice (or syrup) and about half of the cold buttermilk into the blender and puree until smooth.

Pour in the remaining buttermilk and briefly continue blending on the lowest setting until everything is evenly combined.

Divide the raspberry shake into 4 tall glasses, top each with whipped cream and garnish with the reserved raspberries; serve with straws.
