I'm not saying to drink this "every day", but it is the recipe to use when you just want a darn good margarita.
1-2 shots lime juice, fresh squeezed
2 shots water
1-2 shots tequila, (Blanco is my fave)
1 shot agave nectar
Mix all ingredients in shaker and give it a few shakes. Pour into a glass rimmed with salt or tajin. If you like it sweet then rim your glass with agave.
