Why use baby potatoes?
Baby potatoes or new potatoes are basically young potatoes. They are picked and harvested before they've reached their full maturity and size. And because they have been harvested early, the sugars in the potato haven't turned into starch yet. So, baby potatoes have a creamy and sweeter flavor than mature potatoes. They also have thin skin so you may enjoy them skin-on and they look lovelier with fuller flavors.

What You'll Need
