I can’t choose just one! XD
(Can there be an “all of them” option?)
For soups, great in just about any soup, especially cheeseburger soup (or any cream-based soup, really)
So far I haven’t tried any potato-based casseroles other than scalloped potato casserole
Potato chips yes
Fries if they’re thin (like a combination of chips and fries)
Potato pancakes, yes
-This includes potato mochi
