Ay, Caramba!

Directions

1. 1
   Run the lime half over the rim of a glass and salt the rim.
2. 2
   Squeeze the lime into a cocktail shaker, add the jalapeno slices and cilantro leaves. Muddle lightly.
3. 3
   NOTE: I didn't muddle at all - I thought it would be too spicy. The way I made it had a kick but didn't burn your mouth.
4. 4
   Add remaining ingredients.
5. 5
   Add ice and shake for 20 seconds until ice crystals form.
6. 6
   Pour into glass and serve.
