PLEASE, I BEG OF YOU: DO NOT ATTEMPT TO MAKE THIS DRINK WITH A MIX!
Mixes are all poor substitutes for real ingredients and you will have no use for unused mix. Use limeade instead. Either the frozen concentrated kind or not-from-concentrate type are both good. They should contain real lime juice, sweetener and water (if already prepared).
--Take a 12 oz glass and put a few ice cubes into it.
--Add one shot of Tequila (I recommend Cuervo Especial)
--Fill the remaining space in the glass with Limeade.
--You may wish to salt the rim of the glass with kosher salt and garnish with a wedge of fresh lime.
It is still early Spring here in New England, but my hope is that if we start to act like it is Summer, then Mother Nature will get with the program.
ADDED: It kind of worked: Yesterday started bleary, then got sunny and nice, then rained, then got sunny again and finally got cold and drizzly.
