This is the only way I like a margarita. No sugary mixes, just straight, delicious ingredients.

What you'll need: Serves 1
1 tsp salt + 1 tsp sugar mixed for the rim
1 tsp agave for the rim (and a swirl inside the glass if you like it a little sweet)
2 oz tequila blanco
2 oz orange liqueur (I like Grand Marnier)
Juice from a whole lime
3 oz club soda or lime sparkling water
