   Add water to cover by 2 inches and bring to a boil.
6. 6
   Lower the heat to gently simmer for about 1 1/4 hours, or until the beans are very soft.
7. 7
   Some will split open.
8. 8
   Press on one, and it should crush easily with little pressure.
9. 9
   Remove from the heat and drain in a mesh strainer; let drain for 5 minutes to remove excess moisture.

    Wash the saucepan.
11. 11
    Combine the beans and the white and brown sugars in a food processor.

    Puree into a smooth chocolate-brown mixture, pausing to scrape down the sides if necessary.
13. 13
    Combine the oil and pureed beans in the saucepan and heat over medium heat.
14. 14
    Stir frequently for about 5 minutes, or until the beans have pulled away from the sides of the pan and thickened into a soft paste.
15. 15
    The paste will darken as it cooks and dries out.
16. 16
    Transfer the paste to a bowl and set aside at room temperature to cool completely.
17. 17
    To prevent drying and promote even cooling, occasionally stir the paste as it sits and thickens.

    Use the paste after cooling.
19. 19
    Refrigerate it for up to a week or freeze for up to a month.
