The answer to this question depends on the size and type of potato you're using. For example, if you're using small, new potatoes, you might get around 6-8 potatoes in a pound. But, if you're using larger, Russet potatoes, you might only get 2-3 potatoes in a pound.
This disparity in numbers can make a big difference when following a recipe. Imagine making a big batch of potato salad for a family gathering, only to realize you've added way too many (or too few) potatoes! It's a potato predicament that can be avoided with a little knowledge and planning.
