It’s morning. Probably. You’re disoriented, the inside of your mouth has been replaced by ass-flavored shellac, and somehow it’s 87 degrees at 10 a.m. The full weight of last night will soon come rushing back to you, and you need enough hair of the dog to qualify as taxidermy in order to steel yourself against the impending nausea.
Micheladas are not a challenging thing: Pour beer into a glass, shake in some hot sauce or sauces, squeeze in a lime, salt well. Everyone has their own way of doing it, their own set of ratios, their own sauce. I make mine in a can.
To makes things even easier, start with a beer that is already mixed with tomato juice (Sol makes one). I’m really not a fan of the Michelada, but I’ve seen people make them the way you describe starting with the tomatoey beer.
