Mix all the dry ingredients together except the nigella seeds. Add enough water to combine and form a dough. Knead for 5 mins and set aside.
Portion the dough into 4 balls. Roll out each as much as you can and brush with the butter. Sprinkle with the nigella seeds and a pinch of salt then roll tightly into a tube. Coil the tube in on itself, tucking the end underneath itself. Roll out and repeat with the butter twice.
Heat 1 tbsp butter in a pan and fry the malawach on a medium high heat on each side until golden.
