Small corn dumplings cooked in a rich bean broth from Yucatán offer hearty comfort. This vegetarian, family-friendly dish is a healthy source of protein from beans and corn.
In a medium bowl, mix masa harina with 1/2 cup warm water and 1/2 teaspoon salt. Knead until a soft, pliable dough forms. Cover and let rest for 10 minutes to hydrate.
With damp hands, shape the dough into small thumb-sized dumplings. Press a small indentation in the center of each to help them cook evenly.
Heat olive oil in a large pot over medium heat. Add chopped onion and sauté for 3 minutes until soft, then add garlic and cook for 1 minute until fragrant.
Pour in the cooked black beans with their liquid and add epazote if using. Bring to a gentle boil, then reduce the heat to low so the broth simmers steadily.
Carefully drop masa dumplings into the simmering bean broth, stirring occasionally to prevent sticking. Simmer uncovered for 25–30 minutes, until dumplings float and are cooked through (they should be tender but not mushy). Season with remaining salt and black pepper.
Turn off the heat, taste and adjust seasoning if needed. Ladle into bowls and garnish with chopped cilantro before serving.
