It’s really difficult to replicate recipes away from their native settings, especially if you’re not very familiar with what good results should taste like.
I remember going to be in my college roomie’s wedding in Kansas City, MO. Most of the wedding party had all gone to the same college in Texas, so when we went in some restaurant and someone noticed they had fajitas, most of them ordered them. Several had had any since graduation. And we were in beef country, so how bad could they be?
Although everything looked right, it smelled right, and the beef was juicy & tender. But the flavor was a massive disappointment. It wasn’t even in the same flavor orbit as real Tex-Mex fajitas. Blaaaaaaaand.
