Sigeumchi-doenjang-guk (Spinach Soybean Paste Soup)

Spinach is not a year-round promise, no matter what the supermarket says. In the cold months, the leaves grow low and sweet, and a bunch from the market can season a whole pot of guk if you do not smother it. Cook the month you are standing in: this soup is at its best from late autumn through spring, and in tired summer spinach I would rather make eolgari-baechu-doenjang-guk (young cabbage soybean paste soup) than pretend the season does not matter.

Sigeumchi-doenjang-guk is the weeknight soup that sits beside rice, kimchi, and one small banchan when nobody has the strength for a louder meal. My mother made it thin, not like jjigae, and Master Seong-nyeo would tap the spoon against the pot if I reached for more paste. Two tablespoons for six cups of broth. Taste after it simmers, then decide. That is how the spinach still reads green and sweet.

Tonight it asks only three honest things: wash the spinach until the basin is clean, pull the kelp before bitterness starts, and stop cooking once the greens relax into the broth. 손맛 is real; I measure it anyway, because a mild soup is where guessing most often goes wrong.
