Didn't have limes, but had a bag of tangerines, so decided to give it a try:
Juice from 4 fresh-squeezed tangerines
2 oz. Blanco tequila (I used Cuestión)
1 oz. TripleSec
1 tbsp Agave Nectar
Add a little water.
Shake over ice and serve. Strain if you don't like pulp.
Garnish with slice of tangerine.
It is very sweet,, I might try some bitters or sour mix next time.
