What is the difference between 'chashu' and 'kakuni'?

Chashu and kakuni are both popular pork toppings for ramen, but they have some key differences. Chashu is made from pork belly that is rolled into a log, tied with string, and then simmered in a sweet and savory sauce. Kakuni, on the other hand, is made from thick cubes of pork belly that are slowly braised until they are tender and flavorful. Chashu is typically sliced thinly, while kakuni is served in thick chunks. Both are delicious, but they offer different textures and flavors.
