Creating perfect Purple Sweet Potato Roti is easy if you follow these steps:

1. Prepare Sweet Potato: Boil the purple sweet potato until soft. Let it cool, then peel and mash it until smooth.
2. Mix Ingredients: In a large bowl, combine the mashed sweet potato, whole wheat flour, and salt.
3. Knead Dough: Gradually add water and oil while kneading the mixture until a smooth and soft dough forms. Cover it and let it rest for about 15 minutes.
4. Divide the Dough: After resting, divide the dough into equal-sized balls, roughly the size of a golf ball.
5. Roll the Roti: On a floured surface, take one dough ball and flatten it slightly. Using a rolling pin, roll it out into a flat, round shape, about 6-8 inches in diameter.
6. Cook the Roti: Heat a skillet or griddle over medium heat. Place the rolled roti onto the skillet and cook for about 1-2 minutes on each side or until light brown spots appear.
7. Finish with Ghee: For added flavor, spread a little ghee or butter on each hot roti before serving.
