I don't even like tacos from northern or central mexico, so mexicans are also to blame for not making superior tacos to sourthern mexico's tacos, hence our gringo neighbors gave it a shot of making their own.
Central and northern parts of mexico is where the taco starts to degrade and become abominations lack of gastronomic culture and socioeconomic factors. For word limit purposes I will focus on the suadero taco ( beef's skirt ) which is served around mexico
Southern Mexico tacos ( veracruz, yucatan, chiapas, oaxaca, guerrero ):
1) The beef skirt:
pre-marinated at home with grass fed cows ( the meat is not bought at walmart, which basically comes from U.S as a cheaper alternative and lesser quality, or in pre-marinated industrial packages like sukarne brands at supermarkets )
2) tortillas:
Mostly handmade, but they have a different recipe for factory tortillas which do not break if they are cold
3) salsas:
the classic ones, red, green, pico de gallo and guacamole. But also peanut, habanero/manzano/jalapeΓ±o/chipotle curtido
Central Mexico tacos ( cdmx, jalisco, guanajuato)
Northern Mexico tacos ( baja, sonora, chihuahua, monterrey):
