The michelada is probably my favorite summertime drink, an incredibly refreshing beer cocktail made of a Mexican pilsner-style beer with tomato juice, hot sauce, lime juice and salt. Why not, we wondered, serve it up in frozen form? Sure, it's not as sweet as most ice creams, but what could be better for a summer afternoon than frozen beer? This ice cream is actually quite savory. There's as much salt in the recipe as sugar.
