Home Kimchi — The Maangchi Method

What kimchi is

Kimchi is the family of Korean fermented vegetables. Baechu kimchi — made with napa cabbage — is the canonical version, but there are 200+ documented kimchi varieties using radishes, cucumbers, scallions, mustard greens, and other vegetables.

This is the baechu version, more or less the Maangchi method, scaled to a single 2-liter jar.

Recipe (1 large jar, ~1.5 kg finished kimchi)

Day 1 — Salting (start in the morning)

1 medium napa cabbage (about 1 kg)
½ cup coarse sea salt or kosher salt

Day 1 — Paste (make in the afternoon while cabbage drains)

1 tbsp glutinous rice flour (or 2 tbsp all-purpose flour)
1 cup water
½ medium onion
6 cloves garlic
1 tbsp minced ginger
¼ cup Korean fish sauce
¼ cup gochugaru (Korean red pepper flakes — must be Korean, not generic)
2 tsp sugar
1 medium daikon radish (about 300g), julienned
4 scallions, cut into 1-inch pieces
½ medium carrot, julienned

Method

Salting (morning):

Quarter the cabbage lengthwise, keeping the core attached.
Soak the quarters in water briefly, then sprinkle salt between each leaf — pulling the leaves apart enough to get salt in.
Pile the salted quarters in a large bowl. Let sit 2 hours, turning every 30 minutes. The cabbage will release water and become bendable.
After 2 hours, rinse the cabbage 3 times under cold water to remove most of the salt. Squeeze gently. Drain in a colander.

Paste (afternoon):

In a small pot, whisk the glutinous rice flour into the cup of water. Bring to a simmer, stirring, until it thickens into a thin paste — about 3 minutes. Cool.
Blend (food processor or mortar) the onion, garlic, ginger, fish sauce. Combine with cooled rice paste.
Stir in gochugaru and sugar. Add julienned daikon, scallions, carrot. Mix into a thick red slurry.

Assembly:

Wearing gloves (gochugaru stains and burns broken skin), pull the cabbage leaves apart and rub the paste between every layer — about 1 tablespoon per leaf layer.
Pack the painted cabbage into the jar, pressing down to release liquid. Leave 2 inches headspace.
Cover loosely (the kimchi will produce CO₂ and pressure). Leave at room temperature 24-48 hours.
Taste at 24 hours. If it tastes sour and is bubbling, move to the fridge. If still bland, give it another day.

Storage

Refrigerated, kimchi keeps for months. The flavor continues to develop — milder in week 1, sharper by week 4, increasingly fizzy and sour by week 6. All of these stages are correct kimchi; use the milder version fresh in salads or with rice, and the older version cooked into stews and pancakes.

Notes

Korean gochugaru is non-negotiable. Generic red pepper flakes are too hot and have the wrong flavor profile. Buy a 1-pound bag once; it lasts a year.
The cabbage-salt step controls everything. Under-salted, the cabbage is too tough; over-salted, the kimchi will be inedibly salty. Two hours, three rinses, gentle squeeze.

Reading

Maangchi's Maangchi's Real Korean Cooking (2015) has the full Maangchi method. Lauryn Chun's The Kimchi Cookbook (2012) has 100+ variations on the basic technique.

The Maangchi reference

Emily Kim (known online as Maangchi) is the most-watched
English-language Korean cooking instructor. Her YouTube channel
(launched 2007) has become the standard home-cook reference for
Korean cuisine; her 2015 book Maangchi's Real Korean Cooking
and 2019 Maangchi's Big Book of Korean Cooking are the
companion print references.

Her kimchi recipes — and the broader fermentation
preparations — are the cleanest English-language source for
authentic home kimchi making. The technique is documented with
both written instructions and video, which matters because
several steps (the salt-massage, the consistency of the rice-
flour paste, the seasoning paste consistency) are easier to
understand visually.

The basic napa cabbage kimchi

The dish has roughly 200 distinct traditional variations; the
napa cabbage version is the most common and the entry point.
The Maangchi method:

Salt the cabbage. Cut the napa head into quarters, salt
liberally, let sit 2 hours, flipping once. The salt draws
water out of the cabbage and softens the leaves.
Rinse and drain. Wash off most of the salt; squeeze
gently to remove water.
Make the seasoning paste. Combine gochugaru (Korean
red pepper flakes), minced garlic, ginger, fish sauce (or
anchovy paste), and a cooked sweet rice flour porridge.
Apply the paste. Massage into every leaf of the cabbage.
Pack into jars. Leave the jars at room temperature for 1 to
2 days; then refrigerate.

The fermentation timeline

The ferment is active for the first 1 to 2 days at room
temperature, then slows under refrigeration. The kimchi is
edible after the first day; it improves over the first week;
peak flavor is typically 2 to 4 weeks in.

After 6 to 8 weeks the kimchi continues to ferment slowly and
becomes more sour. The sour mature kimchi (mukeunji) is the
ideal ingredient for kimchi jjigae (the stew) and other
cooked-kimchi preparations.

Sourcing the ingredients

Gochugaru. Korean red pepper flakes; the dish does not
work with generic chili flakes or paprika. Korean markets
or online retailers (the H Mart chain in the US carries
Maangchi-recommended brands). Should be coarse, bright red,
and not too dry.
Napa cabbage. Look for heavy heads with firm white stems;
yellowed leaves are old.
Fish sauce. Korean fish sauces (the saewujeot fermented
shrimp paste and the myeolchi-jeot anchovy sauce) are
traditional; Thai or Vietnamese fish sauce works as a
substitute.
Sweet rice flour. Different from regular rice flour;
required for the right paste consistency.

Storage detail

Kimchi holds 6 months refrigerated comfortably; some Korean
families keep batches for over a year. The fermentation
continues slowly under refrigeration; the flavor changes over
time but does not spoil within typical home use windows.

Store in glass jars with looser-than-airtight lids — the
fermentation produces gas that needs to escape. Tight-sealed
mason jars can build pressure that pops the seal or breaks the
jar over several weeks.

What to do with it

Kimchi is eaten as a side at every Korean meal (the banchan
tradition). Beyond that, the broader Korean cooking canon
includes:

Kimchi jjigae. The kimchi stew, made with mature kimchi
and pork or tuna.
Kimchi fried rice. Day-old rice plus kimchi plus a fried
egg.
Kimchi pancake (kimchijeon). Kimchi mixed into a batter
and pan-fried.

The vegetable-only versions all work; meat versions add
depth.
