Krupnyk (крупник, barley soup)

Pearl barley looks like nothing in the jar, little grey-white stones that promise you very little. Then it drinks half the pot, swells until the broth turns cloudy and silky, and suddenly you've made dinner from roots, mushrooms, and patience. Krupnyk is pantry soup with a backbone. The spoon must stand up straight.

This is the soup for lean weeks, cold weeks, the week before pay arrives, the day after you thought there was nothing in the kitchen. Dried mushrooms give it the forest smell, potatoes soften into the broth, and the barley keeps going until the pot sounds heavier when you stir it. Aunt Nadia wrote only "cook until it sounds right" on the letter for this one, which was rude of her and also correct.

The one thing that decides the dish is the zasmazhka, the slow-sweated onion and carrot. Add it near the end, not at the beginning. Its sweetness should sit brightly on top of the mushroom broth, not flatten into the stock and disappear. Make a big pot, enough for eight guests or one hungry Ukrainian, because krupnyk thickens overnight and becomes even better for lunch.
