Ingredients:

1/2 cup black beans (placed in a recipient with water, let them sit for at least two hours)
1/2 cup orange juice
1/2 cup sugar
1 cinnamon vine or 1/2 a spoon of lemon or orange zest

Instructions:

Replace the water you used to soak the beans, then cook them without salt and the cinnamon vine.

Once cooked crush them and strain them, add then the orange juice.

Heat the sugar along with the orange zest and a cup of the water that you boiled the beans with. Keep the preparation in medium heat moving constantly.

When the mixture has lightly thickened, add the beans and continue to stir until you can see the bottom of the recipient. Let cool, refrigerate and serve.

Tips: Do not let the sugar burn, stir constantly, no one (at least no one I know, likes the taste of burned sugar)
Make sure you use black beans, if you change the beans you use, so will the taste.
