Saturday Cocktails : Margaritas

Inspired by this week's Minimalist column, I had to make cocktails. To go along with the planned grilling it didn't take much thinking for me to settle on margaritas as the drink of choice. I did a bit of small-scale playing around to get proportions I liked and ended up with the following (for two drinks):

4 oz good tequila (I used Herradura anejo)
2 oz lime juice (freshly squeezed, of course)
1-1.5 oz triple sec (actually curacao triple sec, which is nice stuff, too sweet to drink pure of course, but it has a nice flavor)

Shake with ice cubes and then serve over an ice cube, garnished with a bit of lemon zest.

Very nice stuff to sit in the sun and sip.

Update, 27 July:
After some more experimenting, the final proportions we settled on for this drink were 4 : 2 : 2. The triple sec brings a nice roundness and some bitter notes, so we increased the proportions a bit.
