Black Bean And Poblano Tacos

Step 1

Drain beans, put in medium pot, add water to cover and bring to a boil over hight heat. Add onion, bay leaf, epazote and salt and reduce heat to a gentle simmer. Cook for about 1 hour, longer if necessary, adding water occasionally if liquid falls below surface of beans. When beans are tender, taste and adjust salt. Keep beans warm in their broth.

Step 2

Meanwhile, roast poblano chiles over a charcoal grill, under the broiler or directly on a gas stovetop burners until skins are completely blackened and blistered. Set chiles aside to cool, then split lengthwise. Scrape away skins and seeds with a paring knife. Cut cleaned chiles into 1/2-inch ribbons, transfer to small bowl and season lightly with salt.

Step 3

To serve, warm the tortillas on a hot griddle or cast iron pan over a burner. Put 2 warm tortillas side by side on a small plate. With a slotted spoon, place 2 tablespoons beans on each tortilla. Top with a few shreds of mozzarella and 2 or 3 strips of poblano. Crumble a little queso fresco and drizzle about 1 teaspoon crème fraîche on each taco.
