I finally found a great little place that sells some stuff here in Dresden. It's called El Mercadito and it's the only place I can find chorizo here...which is great cuz I can't live without breakfest tacos. Forget about those store bought tortillas too. Here's a great vid that goes over the recipe. It takes time and patience but is well worth the effort.
