Found a good one. Really really dangerous.
It’s a grapefruit gin and tonic.
Use a vegetable peeler to take off a few grapefruit rinds. Make one long one for garnish. Put the rinds in a shaker and squeeze a lime on top of the rinds. You can add simple syrup or some stevia on top of you wish. Muddle. Add ice, a few ounces of your favorite gin and fresh grapefruit juice. Shake. Pour over ice in a tall glass and top with tonic.
They go down fast. Plan for a headache in the morning.
