I love the fluffy soft King's Hawaiian Sweet Rolls but they are cloyingly sweet for me. A lot of copycat recipes online also have a ton of sugar and some have pineapple juice. Because...Hawaii. Um, yeah. On the list of countless ingredients is potato flour. According to numerous baking blogs, addition of mashed or flaked potato makes breads extra moist and fluffy soft and it also helps in keeping the bread stay fresh longer.
