Bartender Alisia Ouellett made this one night after trying the . Blood Clot. “. It is extremely popular at Sam’s SPorts Bar in Springfield Ma and is slowly making its way to other hot spots. Pour Red Bull® Energy Drink (roughly half of a small can) and a splash of Gin into a large jigger filled with Ice. Strain into a highball glass. Using the same jigger filled with new or the same Ice pour the Southern Comfort® into a Shot Glass. Drop the shot into the red bull and guzzle.”
