So, not today, but recently… I was in a Mexican restaurant sitting at the bar. The US v Mexico soccer game was on so it was a little crowded and all of us at the bar got to chatting.
And a Latino guy was drinking something in a clay cup, I asked what the heck it was. A cantarito, it turns out. Grapefruit, orange, and lime juices, tequila, topped with grapefruit soda. With tajin on the rim. I ordered one, really solid.
