Place the sweet potato sticks in a bowl, add the oil and mix everything together well.

Sprinkle the durum wheat semolina, the spices and the salt over the sweet potatoes and mix everything together thoroughly once more.

Place the sweet potatoes on a baking tray lined with baking paper and bake in the middle of the oven at 200 degrees (top and bottom heat) for about 45 minutes. Turn the fries several times on the tray whilst baking.
