If you are in MD, you can buy them if you ask at the Mexican restaurant in the Rio complex in Gaithersburg (Rio Grande? Unclue Julios? I'm completely blanking on the restaurant name). If you aren't eating there you can just walk up to the bar and ask. They make them fresh on site.
Trader Joe's Handmade Tortillas (make sure they say Handmade as the other ones aren't as good) are pretty good for grocery store bought ones.
I don't think the grocery ones are fine, however...to me they taste terrible when I compare them to those restaurant ones! I'd love to find some that are just as good. Maybe WF or TJs?
I'm not super in the kitchen so I'm not really looking for a recipe unless it is foolproof. I just want to buy some really amazing restaurant tortillas! I went to Silverado over the weekend and took some home as leftovers. They are fantastic, even made myself a quesadilla out of one. Anyone know of a place I could buy high quality tortillas? TIA
