3 tablespoons white wine vinegar or fresh lime juice
1/2 teaspoon dried oregano
1/2 teaspoon ground cumin
salt and pepper
for the soup...
1 pound black beans, picked over and rinsed
2 bay leaves
5 cups water
1/8 teaspoon baking soda
1 teaspoon salt
3 tablespoons olive oil
2 medium onions, peeled and finely chopped
2 large carrots, peeled and diced
4 cloves of garlic, minced
5 cups vegetable stock
2 teaspoons ground cumin
2 teaspoons dried oregano
2 tablespoons white wine vinegar or lime juice

To make the marinated rice, combine the first seven ingredients in a mixing bowl (if your rice has just been cooked, be sure to cool it to at least room temperature before combining with the other ingredients.)
Season with salt and pepper to taste.
Marinate for at least one hour or up to one day ahead (cover with plastic wrap and keep chilled in the refrigerator overnight; bring to room temperature before serving.)
Place the beans, bay leaves, water and baking soda in a large pot with a tight-fitting lid.
Bring to a boil over medium-high heat.
Stir in the salt, reduce the heat to low, cover and simmer until the beans are tender (1 to 1-1/2 hours.)
Discard the bay leaves and set the cooked beans aside (do not drain.)
Heat the olive oil in a 5-quart pot over medium heat.
Add the onions, carrots and garlic and cook, stirring occasionally, until the onions are translucent and the carrots are softened (about 5 minutes.)
Add the stock, cumin, oregano, vinegar or lime juice, and black beans along with their cooking liquid.
Cover and simmer, stirring occasionally, for 30 minutes, adding more stock if a thinner soup is desired.
Add salt and pepper to taste.
Serve the soup in bowls topped with spoonfuls of the marinated rice.
