Its name means 'little dance' in reference to how fiery the sauce is — a nod to the punch of derssa, Algeria's garlic-and-chili paste, that defines the whole chtitha family of dishes.
Chtitha batata simmers potatoes in a red sauce built on derssa (a garlic and chili paste), tomatoes, and warming spices until the potatoes turn deep orange and soak up the heat. This meat-free version built around potato is a favorite home dish in the Ghardaïa region.
