Ok, I'm embarrassed to admit it, but I don't know how to make a real Margarita.

I buy mix at the grocery store, and the cheapest tequila I can find at the state liquor store, and randomly mix them together in a salted-rim glass.

Teach me! Mold me! Show me the way to true Margarita bliss! Gimme your favorite recipes!

(ps: I like 'em on the rocks rather than blended. Sometimes with no ice at all.)
