"A bowl of ramen consists of four basic elements: the broth, the tare, the noodles, and the toppings. The broth is generally a mix of pork, chicken, seafood, and vegetables, with each shop crafting their own blend. Most mix various parts of pig and fowl, some add more complex elements, and some never reveal their secrets. Though most diners categorize ramen into shoyu, miso, shio, and tonkotsu types, many shops specialize in just one style, referred to simply as “ramen” on their menu. This guide details the basic characteristics of a number of established regional styles; it only scratches the surface of the myriad varieties of ramen being served every day across Japan." - rønin
