Step 1

Place nutritional yeast in a small bowl or measuring cup and pour in ⅔ cup hot water; stir to combine. Set aside.

Step 2

Heat 2 Tbsp. oil over medium in a medium pot. Add onion and ½ tsp. turmeric, season with salt, and cook, stirring often, until onion is softened and starting to brown around the edges, 5–7 minutes.

Step 3

Add miso to pot and finely grate in 3 garlic cloves. Cook, stirring and smashing down on miso constantly, until miso starts to darken and stick to the bottom of pot (similar to tomato paste), about 2 minutes. Add chickpeas and stir to coat. Carefully pour in golden liquid that’s floating atop the reserved soaking nutritional yeast, leaving as much of the sediment behind as you can (about ½ cup should remain but don’t stress if a little slips in); discard. Add 4 cups water. Increase heat to high and bring to a boil. Reduce heat so mixture is at a gentle simmer, cover pot, and cook soup while you make the dumpling batter.

Step 4

Whisk together chickpea flour, baking powder, cayenne, ½ tsp. salt, and remaining ¼ tsp. turmeric. Season generously with black pepper. Add dill, ⅓ cup yogurt, 4 Tbsp. oil, and 2 tsp. warm water, then finely grate in remaining garlic clove. Stir with a wooden spoon or rubber spatula until no dry spots remain. Your dough should be thick and sticky.

Step 5

Using damp hands, form dough into 10 balls (the easiest way to do this is to divide the dough in half, then divide each half into 5 pieces); place on a cutting board as you go. Gently drop dumplings into soup, cover pot, and simmer gently, until dumplings puff dramatically and float to the surface (to check for doneness, take 1 out and cut it open; it should be cooked through—the interior should look soft and not too dense), 7–9 minutes. Add celery, being careful not to smush dumplings, and simmer, uncovered, until celery is crisp-tender, about 3 minutes. Season broth with salt and black pepper.

Step 6

Ladle broth and dumplings into bowls and top with a dollop of yogurt. Drizzle with oil and season with more black pepper.
