In a cooking pot/ sufuria, heat up the cooking oil and add the diced onions, carrots, minced garlic, ginger & turmeric. Keep stirring & let them cook on medium-high heat until the onions are soft & garlic is fragrant for about 3-4 minutes.
Add in the coriander stems and cook till fragrant. Remember to season with black pepper & sea salt.
Add in the pre boiled butter beans & mix them in. Then add the water and mix in. Turn down the heat and let this simmer for 10-15 minutes while covered.
Add in the chopped up fresh coriander (dania) leaves. Mix them in then turn off the heat.
Transfer the soup ingredients to a blender and blend on high for about a minute or two or until creamy. You can add more broth or water for a thinner consistency. (See Blending tips here.)
Once blended, add back to the cooking pot and reheat before serving.
Serve while hot. You can garnish with some butter beans and fresh coriander (dania) leaves or any other garnish of your choice and enjoy.
