All those bright green things in the box just look like Spring, don’t they? The “ground bean paste” in the recipe is a Chinese iteration of a dark miso that is finer than most standard miso pastes, and is more liquid, so it mixes into the dish more readily. Miso can be used as well, just thin it with some water until it is slightly pourable. The shrimp are an option of course, but they look pretty against all the greens, and the flavors go well together. To omit them simply start the recipe right after the shrimp get removed from the pan.
