The Bottom Less Pit

Combine the water and sugar in a small pot. Bring to a boil, then add 1 sliced jalapeño. Keep the seeds if you'd like the syrup a little spicier or discard if you'l like the syrup with just a hint of spice.
Lower the heat and allow to simmer for 10 minutes. Stir occasionally and remove from heat once all of the sugar is mixed again.
Pour into a mason jar (with the jalapeño slices) and allow to cool to room temperature before refrigerating.
Instructions for the Margarita
Add the tajin to a shallow plate, then run a slice of lime along the edge of two small cocktail glasses. Invert each glass, one ate a time, and roll in the tajin to coat. Add ice and refrigerate the glasses.
Peel the cucumber, then dice. Add to a large glass or bowl and muddle by pressing against the cucumbers until crushed.
Strain the liquid into a cocktail shaker filled with ice. Then add 4 ounces of chilled tequila, 2 ounces of lime juice and 2 ounces of the jalapeño simple syrup.
Shake vigorously for 30 seconds before straining into the two refrigerated glasses.
Serve with sliced jalapeños or cucumbers and enjoy!
