How to Make It
Using a sharp knife, remove stems from collard greens. Cut leaves into 2-inch squares (about 14 cups), and rinse in cold water.
Heat olive oil in a 4-quart stockpot over medium. Add bacon; cook until crisp, about 10 minutes. Transfer bacon to paper towels to drain, reserving drippings in pot. Crumble bacon, and set aside.
Add onions and garlic to hot drippings in pot, and cook over mediumv, stirring often, until golden brown, about 25 minutes. Add ham hocks, and cook until browned on all sides, about 5 minutes, turning ham hocks every 45 seconds. Add bourbon and vinegar, and cook, stirring and scraping up browned bits on bottom of pot, until liquid is reduced by half, about 30 seconds. Add 8 cups cold water; bring to a simmer.
Add salt and pepper to soup. Add collards in large handfuls, stirring each addition until wilted, 2 to 3 minutes, before adding next handful. Return to a simmer; cover and cook until collards are tender, about 1 hour.
Remove ham hocks; cool slightly. Pull meat from bones, and chop meat. Discard bones and skin.
Divide soy sauce evenly among 4 serving bowls. Ladle 1 1/4 cups liquid from cooked collards into each bowl. Divide noodles evenly among 4 bowls, and stir noodles twice in broth to combine.
Top bowls evenly with ham hock meat, collards, eggs, bacon, scallions, lime wedges, and shichimi togarashi.
