In the 14th century, in a small village high in the mountains, a little girl named Ana loved to help her grandmother in the kitchen. Today was special because her grandmother was going to teach her how to make börek, a tasty pastry that everyone in the village loved. “Watch how I roll out the dough,” her grandmother said. Ana’s eyes sparkled as she saw the thin, shiny sheets. “Now we cut it into triangles!” her grandmother announced.
Ana carefully used a wooden knife to cut the dough. “Why triangles, Grandmother?” she asked. “Triangles are strong and hold the filling best,” her grandmother explained. Ana was excited to learn that these were special isosceles triangles, with two equal sides and one base. “Just like in my math book!” she said.
