@ysmina-- I agree with you about the taste, but like you said, you get used to it in time. I personally think that potato flour is a lot healthier than regular white flour. And it's also great that it's suitable for gluten-free cooking.
Something else you can add to get rid of the potato taste, especially if you're making cookies or muffins is to add some applesauce in the dough. It makes the dough softer because it adds moisture and it also takes away the potato taste a little bit.
This is not much of a problem if you're adding just a little bit of potato flour to make soups and gravies thicker. It actually works perfectly this way.
