About this dish
Jangajji - vegetables preserved in soy brine - was the Korean kitchen's answer to long winters and months without reliable food storage.

This zucchini version layers thick half-moon slices with onion, cheongyang chili, and whole garlic cloves in a sterilized glass jar before a boiling-hot brine of soy sauce, vinegar, sugar, and water is poured straight in. The heat from the brine does two things at once: it partially cooks the outer surfaces while the centers stay crisp, and it drives the pickling liquid deeper into each piece than cold brine ever could. The pickle is technically ready at 24 hours, but after three days the sweet-sour-salty brine has fully penetrated and the flavors integrate into something more balanced. Cheongyang chili contributes a slow-building heat at the back of each bite, and the whole garlic cloves shed their raw sharpness in the brine, softening into something mellow and slightly sweet. Unlike fresh banchan that must be eaten the same day, this keeps for two weeks in the refrigerator - a ready supply of bright, tangy contrast for any meal that needs it.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Wash 600 g Korean zucchini, dry it well, and slice it into 0.8 cm half-moons.
If the seed core looks large or watery, trim out a little of the center to keep the pickle from turning soft.
- 2Heat
Cut 120 g onion into thick 1 cm strips, and prepare 20 g Cheongyang chili and 30 g whole garlic cloves without surface moisture.
Sterilize a glass jar with boiling water, then let it dry completely before filling.
- 3Control
Layer the zucchini, onion, Cheongyang chili, and whole garlic cloves alternately in the jar.
Press only lightly to reduce empty spaces, because packing too tightly can bruise the zucchini and make it soften during pickling.
- 4Control
Put 180 ml soy sauce, 120 ml vinegar, 90 g sugar, and 180 ml water in a pot over high heat.
When the edges begin bubbling, stir until the sugar fully dissolves and the brine reaches a vigorous boil.
- 5Heat
As soon as the brine is boiling hard, turn off the heat and pour it slowly into the jar.
Make sure all vegetables are submerged, and if pieces float up, press them down gently with a clean spoon.
- 6Finish
Seal the jar, then refrigerate once it is cool enough to handle.
Serve after 24 hours, but for a more even sweet, sour, and salty flavor, wait 3 days and finish it within 2 refrigerated weeks.
