Margarita-ish

Steps

1. 1Pour 1/2 fluid ounce of the tequila into a small saucer. Spread the kosher salt in a separate small saucer. Dip the rim of a wide-rimmed glass into the tequila. Lift out of the tequila and hold upside down for 10 seconds to allow for slight evaporation. Next, dip the glass into the salt to coat the rim. Set aside.
2. 2Halve the lime. Cut a thin slice for garnish and set aside. Juice lime and orange into a measuring cup through a sieve. You should end up with approximately 2 fluid ounces of juice.
3. 3Pour juice into a Boston-style cocktail shaker, add the agave and remaining 1 1/2 fluid ounces of tequila and any remaining on the saucer. Add the ice to the shaker, cover, and shake for 30 seconds. Strain the mixture through a cocktail strainer into the prepared glass, garnish with reserved lime slice, and serve immediately.
