As a result, I had a Cinco de Mayo Melave Malke*. I served tequila, coronas, nachos, bean dip, 4-layer dip, guacamole, and plain (blue) chips. Also, according to TJ Shroat of In the Pink Texas, most traditional Cinco de Mayo cakes come with a figurine of a (specific) Argentinian Jew on top due to a TV segment.
Kosher "Mexican" food. Cheese, but no meat here!Leah of Accidentally Jewish celebrated Cinco de Mayo with "18 lbs of guacamole," but felt uncomfortable watching the fight, as it is a bloodsport. She said " don't care how big a match it is, it is a violent sport and aren't Jews supposed to abhore the sight of blood?" I'd never heard of that, but I'll make an effort to look it up now. Speaking of looking things up, according to Lindsay William-Ross of LAist (like Gothamist, but for LA). mangoes are the most popular fruit in the world, including with her Jewish grandmother. In the same vein Itai had a vaguely Mexican-themed Shabbat meal, but ran into what I consider the eternal dilemma: ethnic food that is not traditional Jewish (Ashkenaz OR Sephard) food doesn't tend to hold well over Shabbat, because really, who prepares something, and then needs it to sit/heat/reheat for 5-6 or 18 hours?
Of course, I am sure that many Jewish organizations used Cinco de Mayo as an opportunity to hold a singles' mixer (Lauren of Lost in Texas declined to go to one of them), and I guess that is cool, but let's just say that no one talked about the importance of endogamy at my party.
*Melave Malke means "accompanying the queen" and it is traditionally a party/celebration to escort out the "Shabbat Queen" (Shabbat is often personified as a queen). This type of party is popular in Chassidic circles, and is often comprised of drinking, snack foods, and stories about the rebbe. According to some sources Melave Malkes were started by King David, whose death was foretold to occur on a Shabbat, so at the end of every Shabbat he celebrated his continued existence.
