Aehobak-guk (애호박국, Korean Zucchini Soup)

Summer aehobak is a forgiving vegetable until you put it in the pot too early. Then it gives up and disappears. At the market near my childhood house in Suwon, the best ones were pale green and heavy for their size, with skins thin enough that my mother never peeled them. She bought two, not a sack. This soup is for the day you want rice, kimchi, and one clean bowl, not a table trying to impress anyone.

The whole soup lives or dies by timing and salt. Build a short anchovy-kelp broth, season it with saeujeot (salted fermented shrimp), then add the zucchini late, just long enough for the edges to turn translucent while the centers still hold. Notebook 18 says 2 teaspoons of minced saeujeot for 5 cups of water, with another 1/2 teaspoon only after tasting. That number matters because saeujeot can swing from gentle to fierce, and a mild vegetable has no place to hide a heavy hand.

My teacher Master Seong-nyeo would tap the side of the pot when students wandered off at this point. Stay there. Five minutes of attention keeps the half-moons tender instead of melted, and the broth stays clear enough to taste the vegetable. Cook the month you're standing in. In summer, aehobak deserves this bowl; in winter, make radish soup and wait for the squash to come back.
