Galchi-sokjeot (갈치속젓, Salted Hairtail Innards)

Galchi-sokjeot begins at the fish counter, not at the stove. If the hairtail isn't fresh enough for the seller to meet your eye, don't make this dish today. Cook the month you're standing in: hairtail is strongest in the southern markets from summer into autumn, and that is when Jeju and Honam kitchens have the most reason to salt what the fish gives them.

People hear innards and think this is rough food. It isn't rough. It is exacting. You remove the gall bladder because bitterness spreads faster than apology. You salt by weight because a handful from one cook is safety, and from another cook is trouble. For 400 grams of cleaned innards, Notebook 31 says 100 grams coarse salt. That number matters.

This is not a condiment you spoon onto everything to prove bravery. A teaspoon can season a pot of kimchi stew. A tablespoon can deepen a batch of winter kimchi. Minced with garlic, scallion, gochugaru, and a little sesame oil, it becomes the sharp thing beside hot rice that makes everyone reach for one more spoonful. The smell is strong. The work is stronger.

I won't tell you this is easy, because that would be disrespectful to the fish and to you. Keep it cold, keep it clean, keep it measured. Then write down the week you opened it and how much you used in your kimchi. Memory is a borrowed bowl.
