In Mombasa and in Coast generally, most meals are cooked with coconut Milk (Tuwi la Nazi) due to the fact they are in plenty. One of the common dishes cooked in coconut milk is Cassava, or in Swahili Mhogo wa nazi. Basically, it is boiling cassava in coconut milk until it becomes soft and you can serve with papa (shark meat) or grilled fish.
Here is a simple recipe from Fauzia’s Kitchen Fun
500gm cassava, peeled and chopped into small bits
1 cup thick/heavy coconut milk
1 cup thin/light coconut milk
Salt to taste
1-2 green chillies, chopped
Some chopped coriander
1/4 tsp.garlic paste
Juice of 1 lemon
Put the cassava pieces into a pan, and cover with water. Add salt and garlic paste, and a bit of chopped coriander plus the green chillies. Bring to a gentle simmer until the cassava are soft enough for a knife to pierce into them easily. Drain the water and put them back in the pan. Add the thin coconut milk and boil for about 15 minutes on gentle heat until it starts to thicken and the cassava pieces soften some more. Adjust salt and chili (you can add some chilli powder if you like).
Once the cassava pieces are completely soft and most of the thin coconut milk has evaporated, add the heavy coconut milk and simmer for a few minutes, stirring every few minutes until the cassava are well-coated with the thick coconut sauce. Adjust salt, then squeeze the lemon juice and turn off. Garnish with coriander and serve hot with a meat/fish dish of your choice!
