Soba Soup With Shrimp and Greens

Dashi is the sort of super-powered broth that every cook should know how to make. One of the building blocks of Japanese cuisine, the most popular dashi is made from just two ingredients (kombu and katsuobushi a.k.a. bonito flakes) and comes together in fewer than 15 minutes. That makes it the fastest route to a slurp-able, umami-rich broth (with no loooong simmers or bags of chicken bones necessary). Here, it's the base of a super savory soup packed with poached shrimp, nutty soba, and tons o' greens—the perfect antidote to that cold you kinda sorta feel coming on.
