Prepare Ingredients
Gather all ingredients and equipment before starting to ensure a smooth process.
Measure napa cabbage (about 2 kg) and other vegetables (radish, scallions).
Use fresh, firm napa cabbage; optionally add Korean radish and scallions for texture.
Prepare Korean red pepper flakes (gochugaru), garlic, ginger, fish sauce, salted shrimp (saeujeot), and sugar.
Have these ready in small bowls for easy mixing.
Prepare a large bowl, a clean bucket or tub for brining, gloves, and fermentation jars (quart-size).
Ensure all containers are food‑grade and ready for use.
Wash jars, lids, utensils, and cutting board with hot soapy water.
Scrub thoroughly to remove any residue.
Rinse thoroughly, then submerge jars and lids in boiling water for 10 minutes or run through a dishwasher sanitize cycle.
This kills any remaining microbes.
Let them air dry on a clean towel; avoid touching the inside of jars with bare hands.
Use tongs or gloves if you must handle the interior.
Salt the Cabbage
Brining draws out water and creates an environment for lactic acid bacteria.
Cut the napa cabbage lengthwise into quarters, then chop into bite‑sized pieces.
Remove the tough core if desired.
Dissolve 1/2 cup (about 90 g) of non‑iodized sea salt in 4 cups of water to make brine.
Stir until salt is fully dissolved.
Submerge cabbage pieces in brine, ensuring they are fully covered; use a plate to weigh down.
Keep the cabbage submerged to prevent exposure to air.
Peel and mince 6 cloves of garlic and a 2‑inch piece of ginger.
Fine mince releases more flavor.
In a bowl, combine 1 cup gochugaru (adjust for heat), minced garlic, ginger, 2 tbsp fish sauce, 1 tbsp salted shrimp, and 1 tsp sugar.
Mix into a thick paste.
Add 1/2 cup water to loosen the paste; mix until smooth.
Adjust consistency so it coats the cabbage easily.
Mix Cabbage with Paste
Evenly coat the cabbage with the spice mixture.
Drain the brined cabbage and rinse briefly under cold water to remove excess salt.
Taste a piece; it should be pleasantly salty, not overpowering.
Wearing gloves, toss the cabbage with the kimchi paste until every piece is thoroughly coated.
Work in batches if needed to ensure even coverage.
Pack Kimchi into Jars
Pack tightly to eliminate air pockets and encourage fermentation.
Transfer the mixture into clean fermentation jars, pressing down firmly with a clean fist or spoon.
Press out any trapped air bubbles.
Leave about 1-2 inches of headspace at the top of each jar to allow for gas expansion.
Too little space can cause overflow.
Seal jars with lids, but do not overtighten; you can use airlock lids or loosely screw lids to allow gases to escape.
If using regular lids, plan to burp them daily.
Place jars in a cool, dark spot (68-72°F / 20-22°C) away from direct sunlight.
A pantry or cabinet works well.
Check daily for bubbles and smell; after 24 hours, press down kimchi to keep it submerged.
Active fermentation will produce fizz and a tangy aroma.
Taste after 48 hours; continue fermenting until desired tanginess is reached, usually 3-7 days.
Refrigerate once you like the flavor.
Once fermentation is complete, tighten lids and move jars to the refrigerator.
Cold storage slows fermentation and preserves crispness.
Consume within several months; flavors will continue to deepen over time.
Kimchi keeps well for up to 6 months when refrigerated.
