What is Sapporo ramen and what are its key characteristics?

Sapporo ramen is a regional style of ramen from the city of Sapporo in Hokkaido, the northernmost island of Japan. It's best known for its hearty miso-based broth, which is often made with a combination of pork and chicken stock. Sapporo ramen is typically served with thick, wavy noodles that are designed to hold the rich miso soup. Common toppings include sweet corn, butter, bean sprouts, and slices of chashu pork, making it a perfect warming dish for the cold winters of Hokkaido.
