Boil the Mutton to cook for 30 mins with garlic and salt.
After cooking, add chopped the onions, tomatoes, garlic, the potatoes and cover to cook. After cooking, add the chopped Spinach/Sukuma wiki and cook for 5mins.
Bring the water to boil in a sufuria. Add 1/2 cup maize meal to the boiling water. Adding a little bit of the maize flour to the water ensures that the water starts to roar which makes the perfect ugali. Stir using a wooden mwiko/ spatula and try to break any lumps apart.
Add the remaining flour and get stirring. Using the mwiko/spatula, smoothen out any lumps that may have formed. If the ugali is not hard enough, add more flour. Lower the heat and keep working the ugali against the sides of the pot, getting rid of any lumps and also making sure it is evenly cooked.
