It was a few years ago, at about this time of the year, that I went to one of my favorite birrerías, that of Don Prisci's, on the Explanada del Mercado in Pátzcuaro.
That Friday, I was surprised to find that their succulent birria had been replaced by caldos de pescado or camarones and fish plate dinners. Further along, the taquerías were featuring tacos de pescado or of papas y queso y rajas. As a non-Catholic, I'd been unaware of the advent of Lent, or Cuaresma, in Spanish.
Rather than feel deprived, I was pleased by the taste of most of what I sampled during Lent. I blogged these experiences here: http://mexkitchen.blogspot.com/2008/02/la-comida-de-la-vigilia-en-el-mercado.html
I'm looking forward to trying these and other Lenten foods again.
