after a lovely vacation in mexico, i am now interested in recreating some of the delicious dishes. i am trying to figure out what is the best mexican market near me (in fort greene). i am willing to travel to sunset park but would prefer to just hop over to the south slope. the one thing that is a must is nopales (cactus). do most mexican markets sell nopales? if not, i am looking for a place that sells them and also handmade tortillas. thanks in advance for your advice.
