At the shop, I discovered the tortillas come frozen, and at first, I was a bit leery of the whole fresh- frozen oxymoron, but once defrosted, my husband stepped in for a closer inspection, and he practically shed tears of joy at the authentic smell (not to mention the taste). I was able to separate the amount I needed and stick the rest back in the freezer for a later date. Once defrosted, Clint recommends keeping them in the fridge and using them within three days.
