It is a tradition amongst families of Hispanic heritage to have tamales at Christmas. If you do a search on Google for tamales at Christmas you will find stories, poems and recipes all relating to this tradition.
After a rather bizarre Italian Christmas where I ate a lot of fried whitefish I realised there had to be something more ethnic and regional, and more importantly tasty, here in Tejas. That was the first year I tried Tamales from the Dallas Tortilla & Tamale Factory. Beef with jalapeno is my favourite. They also have pork & chicken. They have a number of locations, including Greenville Avenue near Ross & Marsalis Avenue at 8th St. down here in sunny Oak Cliff. Git you some.
