The rich, natural flavor of Joshu's mountain depths

Dinners begin with a rillette of boar and runner-bean miso. The main is chicken thighs cooked in a nutrient-rich broth until it is soft enough to fall off the bone, followed by an invigorating congee prepared in the soup with tangy black vinegar.
