Right now (Thursday evening), people in robes, masks, and tall pointy hats are parading through downtown Madrid. It's not the KKK, it's the Easter processions, a solemn religious tradition. Televised live, too. The hats show that they're penitents, and the masks allow them to do penance in private even though they're surrounded by crowds and TV cameras.
Although globalization has brought chocolate bunnies to Spain, the traditional Easter sweet is Madrid-style French toast, called torrijas: thick slices of bread soaked (not dipped) in milk and eggs, deep fried, then sopped in syrup flavored with cinnamon and lemon peel.
It is eaten chilled, and is not low calorie. A love of torrijas made Queen Isabel II fat.
Madrid's pastry shops will sell about 3.6 million slices of torrijas this season -- this in a city of 3 million residents. Each slice costs about €2 (US$2.66).
You can buy chocolate bunnies, however, and I saw them for sale in my grocery store labeled "Conejos tipo bunny" (Rabbits bunny-style). Bunny? I mentioned this to my Spanish teacher, and she explained that the word as used in Spanish comes from the last name of that cartoon rabbit Bugs -- Bunny -- which by extension has become a nickname in Spain for all rabbits, especially the imaginary type, like the Easter bunny. She did not know that the word existed previous to Warner Brothers.
Globalization brought "bunny" to Spain, via Looney Tunes. ¿Qué hay de nuevo, viejo? (What's up, Doc?)
