Well, if you heard the podcast, you know the recipe: it's equal parts fresh lime juice, tequila, and Cointreau, plus a pinch of sugar, shaken with ice, then strained over fresh ice. The end.
How much for one? Oh, 1 1/2 ounces of each portion, perhaps. Maybe 1 ounce for a shorter drink, about like the one in the picture. Maybe 2 ounces (or 1/4 cup) if you're not planning on doing anything for the evening.
