Where do Patton's potatoes come from?

The correct choice is Idaho and Washington because these states are well-known for producing high-quality potatoes. Idaho, in particular, is famous for its Russet potatoes, which are often considered the gold standard for making fries, due to their flavor, texture, and moisture content. Washington also produces a significant amount of potatoes, complementing Idaho's output. Five Guys sources its potatoes specifically from these regions to ensure that they maintain a consistent standard of quality in their fries, which are a key menu item. This focus on sourcing quality ingredients is essential for delivering the signature taste that customers expect from Five Guys.
