This question is really bothering me. Why are potato onions called potato onions? They are not potatoes. They are onions. They should be called onion onions.
Sorry. That was a recipe. Calling for potato <insert comma> onions <insert another one> and eggs (or some other edible edible).
Punctuation is important.
Potato onions are a type of onion.
I still don’t know why they are called potato onions.
Potato Onions taste just like any other onion, but do not look or taste anything like potatoes. The common name simply reflects their similarity to potatoes in the way they are planted and grown, and how they multiply. Potato onions and shallots are almost never multiplied by seeds, but must be multiplied by planting a bulb in the ground, much the same way you would plant a potato to obtain more potatoes.
Amelia Bedelia would do that very well…
