A bublik is a ring-shaped bread roll that is popular in Eastern European countries like Russia, Ukraine, and Belarus. Similar to a bagel, it's made from wheat dough that is first boiled and then baked, resulting in a chewy texture and a slightly sweet flavor. Bubliks are often topped with poppy seeds, sesame seeds, or salt, and can be enjoyed plain, as a snack, or used as a base for sandwiches and other fillings. They are a staple comfort food and a common sight in bakeries and markets throughout the region.
