Vash, I was born and raised in Mexico and am often surprised by how few Americans (or even Mexicans outside central Mexico) know about sangrita. It is a non-alcoholic chaser, usually made with a tomato or orange juice base. Think of extremely kicked up spicy bloody mary mix..sweet, sour, spicy and delicious. A sip of good tequila and a sip of sangrita is about the perfect pairing. Google for recipes, my family has a great one but I am not at liberty to disclose it.
As for tequilas, there have been a few good ones mentioned. What I drink the most these days is Chamucos reposado, also like the various Don Julio's, Cazadores etc.
