Juice the half a grapefruit and set aside
Juice the lime and set aside. (Save one lime half to rub the rim of your glass.)
Pour Tajin spice onto small plate and turn lime rimmed glass into a layer of Tajin. If you prefer you can use kosher salt instead of Tajin.
Grab a bar shaker and a shot glass.
Add one shot of grapefruit juice to the shaker.
Add a shot of lime juice to the shaker.
Add two shots of tequila
Add half a shot of Patron Citronge
If you prefer a sweeter margarita add a few drops of agave nectar. I like mine very sour so I do without it.
Add ice and shake
Pour over ice into the glass with the Tajin rim. Or serve without ice in glass – your preference!
Get your ‘party’ on!
