I finally stumbled upon (well, stumbled after) the perfecto margarita mix.
Equal parts tequila (anejo or reposado), fresh lime juice and Cointreau. Shake, pour, splash of Gran Marnier. Drink. Rocks, no salt.
ok, this is gonna get weird:
can of lime-aid
can of american, mass-produced, macro brew such as budweiser
fill the lime-aid can with tequila (or 1/2 to 2/3 full)
/not fancy, but damn is it good.
