Wash Dry Red Beans (8 ounce) and soak for at least 8 hours or overnight.
Remove the beans that float to the surface. Add Water (3 cup) and beans to a pressure cooker. The water should cover the beans. Bring the mixture to a boil then lower the heat to a gentle simmer.
Simmer for 1 hour or until the red beans become tender.
Transfer the cooked mixture to a food processor and blend until smooth. Press the mixture through a sieve to remove the red bean skin.
Transfer the paste to a pan. Add Salt (1 pinch), Granulated Sugar (2 cup), and Butter (2 tablespoon). On low heat, simmer the excess water out of the paste. Keep stirring to avoid burning the paste.
