The two biggest shocks for me when moving to Texas from California, is it's just about impossible to get Carnitas, and when you do, it's very bland. The other is that Tri Tip is even harder to find!!!!
And maybe the third shock was how bland all the Mexican food is here. Very little onions, cilantro or spices. They call it TexMex, which to me, means bland and boring.
I've learned that Mexican food is very different in different places, and what I grew up on isn't anything like what everyone here grew up on. Friends that have moved here from CA have also noticed this. It's kind of funny seeing their FB posts when they go home and eat some "real" Mexican food.
