Tommys Margarita for me. My go to version is:
6cl tequila (I like a reposado) 3cl lime juice 1.5 agave syrup
It’s also nice to replace half of the tequila with some mezcal.
I also like to drop a piece of cucumber in the shaker sometimes to get a nice and fresh “vegetal” twist to it.
And it’s pronounced ’gif’ (probably).
