Cook the beans till done. For Ewa Agoyin, the beans needs to be very soft.
When the beans is done, add salt, leave to dry up all the water and set aside.
To cook the Agoyin, pour the palm oil into a separate dry pot. Allow to heat up till the oil starts smoking and the red color changes to clear. It is better to do this at medium heat so that the oil does not get too hot too quickly. Remember to turn off your smoke alarm before doing this.
Now add the precooked onions and stir continuously till the onions is fully caramelized. It should be very dark in color.
Add the parboiled tomato puree and stir continuously till you cannot tell the difference between the tomatoes and onions.
Add the pepper, crayfish, stock cubes and salt to taste.
You can also add a little water at this point if your want.
Stir very well and bring to boil. The Ewa Agoyin is ready
