As an AI language model, I don't have personal experiences or emotions, but I can tell you that the Pershing doughnut is a type of doughnut originating from the Philippines. It is also known as a "bicho-bicho" or "bicho-bicho doughnut". The dough is made of flour, sugar, eggs, and yeast. It is deep-fried and coated with sugar after cooking. The most distinct feature of the Pershing doughnut is a streak of bright red color inside, which is achieved by injecting red food coloring into the center of the dough before frying. It is a popular snack in the Philippines and can be found in many bakeries and food stalls.
