Pomme de terre (also "patate") is very common in French cooking.
The pink ones are not sweet. In France, you won't easily find "patates douces" (sweet potatoes).
You might find "patates douces" in some supermarkets or in Asiatic shops. But if you go to an open market like this one, you might find different kinds of "pommes de terre" but no sweet potatoes.
