The other day I found some corn-flour blend tortillas by tortilla giant Mission--first time I'd ever seen them, and I presume a new product. So I bought.
They're slightly larger than a standard corn tortilla, about 7 inches across but not as large as a standard flour tortilla. You can recognize both parents visually as well as in taste. In thickness they're fairly durable, and though not quite as pliable when super-heated as a flour tortilla, they roll up nicely and it's easy to hold the contents in while eating. I like them!
