Place the hulled beans in a saucepan and cover with water and cook for about 1 hour and 30 minutes or until the beans become soft.
Drain the water and beat the cooked beans with a hand held electric mixer.
Add sugar and a pinch of salt and stir constantly over low heat till the paste texture becomes a little bit thicker. It will become firmer when it has cooled down.
Notes
cooking time does not include soaking beans time over night
