A potato bun is a type of bun made from potato bread, where either potato or potato flour replaces some of the wheat flour. The amount of potato varies depending on the recipe, and some recipes will be made mainly from potato, while others will be mainly made from wheat flour. The potato gives the buns a sponge-like texture, making them soft and fluffy. The potato starch also holds more moisture, allowing the bun to stay fresh for longer. Potato buns are slightly sweet but won’t interfere with the overall experience of the ingredients. They are a good source of carbohydrates and dietary fiber. The potassium content of the potatoes accelerates the yeast activity, causing the dough to rise more quickly. The moist texture comes from the potato starch and its ability to absorb more water. Potato buns are ideal for burgers because they have a neutral flavor that doesn’t interfere with the taste of the burger, and their texture melts in your mouth and highlights the taste of the meat, cheese, and extras. They are also easier to digest due to the action of the potato starch, which disrupts the gluten from forming its network.
