Ruby Gimlet

1 1/2 oz gin (Tanqueray no. 10)
1/4 oz cherry liqueur (Peter Heering)
1/4 oz Rose's lime juice
1/2 oz fresh squeezed lime juice
1/2 oz fresh squeezed ruby red grapefruit juice
1 oz simple syrup

Fill a shaker 2/3 of the way full with ice, combine all ingredients, shake well and serve in a chilled cocktail glass.

G sez: The Rose's mixed with the fresh lime juice was a surprising touch--citrus-y but sweet but not-too-sweet, you know? And psst, J says the name comes from the ruby red grapefruit, but I like to think it was inspired by Salad Fingers's Ruby Tea.
