2 ounces tequila
Freshly juice of 1 lime
Maple syrup, to taste (I add a tiny splash)
Freshly opened bottle of seltzer
Fill a rocks glass with ice. Add the tequila, lime juice, and syrup. Give it a good stir to mix (a chopstick works great here). Add 1 to 2 ounces of seltzer; just enough to give it fizz without watering it down too much. Cheers!
