Place the rice and butter into a skillet over medium heat. Stir constantly, until the rice is lightly browned.
Add the diced tomatoes, El Pato, black beans, water, and cumin. Stir to combine, reduce heat to low (a very low simmer), and cover. Stir occasionally after 4-5 minutes to reincorporate liquid throughout the dish, and then recover and cool an additional 5-10 minutes.
Stir in Gourmet Garden cilantro stir-in paste, chunky garlic, and salt. Taste. Cook additional 5 minutes if necessary, or until the rice is done. (Different varieties of rice will have different cook times.)
Garnish with lime and cilantro, and let guest squeeze lime over the finished rice.
