Preheat oven to 450 degrees Fahrenheit- line baking sheet with parchment paper.
Add madhumbe flour, baking powder and salt to a medium bowl, whisk to combine.
Add butter to the flour mixture and cut in with a pastry cutter until butter is incorporated, even and resembles coarse crumbs.
Pour buttermilk to the flour mixture. Using a wooden spoon, stir in buttermilk until dough comes together. Use the back of the spoon to press dough together until you have a nice dough. Then, using your hands, gently roll dough ball around the bowl to shape and gather all the dough/flour on the side of the bowl. The dough will initially seem sticky but will not stay that way.
Roll out the out about 1" and use a biscuit cutter to cut out about 6 biscuits.
Place in the oven - and bake for 18 minutes or until done. It is done when it has a nice golden colour on top and golden colour on the ridges on the sides.
