My favorite dish is a traditional stew from Spain. 
Cocido madrileño ("Madrilenian stew") is a traditional chickpea-based stew from Madrid, Spain. A substantial and nourishing dish prepared with meat and vegetables: It consists of three courses: broth with vermicelli pasta; chick peas and vegetables, typically cabbage and carrots; and finally, a meat dish of spicy chorizo sausage, boiled beef, chicken, blood sausage (morcilla), chorizo and bone marrow. There are dozens of variants, and everybody says that only their mother really knows how to make it.
My favorite is the Andalusian version, which consists of two courses: the broth, the cheack peas and the vegetables all together as a first course and then the meat and fresh bacon.

Carnival is a public celebration which takes place in many cities and towns in many countries around the world, in February or March each year. Carnival can sometimes last for several weeks. In some places there is only one day of celebration. There are often street parades, bands, costumes and many people wear masks. Carnival is linked to religious traditions in the Catholic and Eastern Orthodox Churches, and it is also linked to local customs. USA Carnival celebrations, usually referred to as Mardi Gras, were first celebrated in the Gulf Coast area of the United States, but now occur in many other states.

Is it a custom in your city to disguise in funny costumes at carnival times?
