Welcome to Curious Daybook

If you’ve spent any time looking into Korean food, you’ve probably already run into kimchi — it shows up in almost every photo of a Korean meal, usually as a small red side dish. What’s less obvious from a photo is that kimchi isn’t one dish. It’s a whole category of fermented vegetables, and the version most people outside Korea have tried is just one of dozens.

This guide covers what kimchi actually is, what it tastes like, how spicy it gets, and how Koreans eat it day to day, plus an easy recipe you can make at home and honest advice on where to buy it if you’d rather not.

What Is Kimchi?

Kimchi (김치, pronounced roughly “gim-chee”) is a general term for Korean vegetables that have been salted and fermented, usually with a seasoning paste built around garlic, ginger, and chili. It’s less a single recipe and more a whole cooking tradition — similar to how “pickles” covers a wide range of foods in English, not just one.

There’s no official count, but Korean cooks have developed well over 100 kimchi variations over time, shaped by region, season, and whatever vegetables were on hand. Three are worth knowing early on:

• Baechu-kimchi – made with napa cabbage; this is what most people mean when they just say “kimchi”
• Kkakdugi (깍두기) – cubed radish kimchi, crunchier and a little sweeter than cabbage kimchi
• Oi-sobagi (오이소박이) – cucumber kimchi, lighter and less fermented, often made in summer

The rest of this guide focuses on baechu-kimchi, since it’s the type you’re most likely to see, eat, or want to make first.

The Most Common Kimchi: Baechu-Kimchi

Baechu-kimchi is napa cabbage salted, seasoned with a chili-based paste, and left to ferment. It comes in a few different forms depending on how it’s cut and where it’s made.

One thing worth knowing: pogi-kimchi (포기김치) and mak-kimchi (막김치) are the same basic kimchi — they’re just cut differently. Pogi-kimchi keeps the cabbage in whole or halved heads, seasoned leaf by leaf; it’s the more traditional, presentation-focused style, often served at a nicer meal or given as a gift. Mak-kimchi is cut into bite-sized pieces before seasoning — “mak” roughly means “rough” or “casual” here — and it’s the everyday version many households make because it’s faster and easier to eat straight from the container. Neither one is more authentic than the other; they’re just suited to different occasions.

Baechu-kimchi recipes also vary by region. As a general pattern, kimchi from colder northern regions tends to be milder and less salty, while kimchi from the southern coast tends to be saltier and use more salted seafood, giving it a stronger flavor. These are broad tendencies rather than strict rules — the exact balance really comes down to the individual cook.

If you’re cooking for someone who can’t handle any spice, baek-kimchi (백김치, “white kimchi”) is worth knowing about. It’s made the same basic way — salted cabbage, garlic, ginger, scallion — but without any gochugaru, the red chili flakes that give most kimchi its color and heat. Baek-kimchi is pale, mild, and slightly sweet and tangy, often with pear added to the brine.

What Does It Taste Like? Is It Spicy?

Fresh baechu-kimchi tastes salty, garlicky, and mildly spicy, with a crunchy texture. As it ferments — whether at room temperature for a day or two, or slowly in the fridge over weeks — it turns increasingly sour and savory, and the cabbage softens. The smell gets stronger and more pungent the longer it ages, which is normal and part of what makes it kimchi rather than a fresh salad.

How spicy it is depends on the recipe:

Spice level	What to expect
None	Baek-kimchi (white kimchi)
Mild	Homemade kimchi made with less gochugaru
Medium	Most standard store-bought and homemade baechu-kimchi, similar to a mild salsa
Hot	Kimchi made with extra gochugaru or a spicier chili blend

How Do Koreans Eat It?

In Korea, kimchi is a banchan (반찬) — a side dish. A Korean meal is typically built around rice and soup or stew, with several banchan set out alongside, and kimchi is one of the most common of all. It’s rarely the main event; it’s there to add crunch, acidity, and spice that balances the rest of the meal.

Because of that role, kimchi is served alongside most Korean meals — rice-and-soup meals, grilled meats, noodle dishes, and fried foods especially. It’s less common with sweeter dishes or desserts, so it’s more accurate to call it a near-universal side dish than something paired with literally everything.

Older, more fermented kimchi also gets used as an ingredient rather than eaten straight — in kimchi jjigae (kimchi stew), kimchi fried rice, or kimchi pancakes. If your kimchi turns more sour than you’d like to eat on its own, cooking with it is the standard move, not a sign it’s gone bad.

Main Ingredients and Where to Find Them

Most baechu-kimchi recipes come from the same core group: napa cabbage, coarse salt, gochugaru (Korean chili flakes), garlic, ginger, scallion, and a salty, savory ingredient like fish sauce or salted shrimp that helps drive fermentation — which is also the main reason most kimchi isn’t vegan. Sugar and a thin rice-flour paste are common additions too, though not universal.

Napa cabbage, garlic, ginger, and scallion are available at any regular grocery store. Gochugaru and fish sauce are the two most people haven’t used before; a Korean or pan-Asian grocery store is the most reliable source, and both are increasingly showing up in the international aisle of larger supermarkets or from online Korean grocery retailers. If you can’t find gochugaru, a mix of sweet paprika and a little cayenne gets closer to the color and mild heat, though the flavor will be noticeably different.

An Easy Way to Make Kimchi at Home

This isn’t a traditional, from-scratch version — it’s a simplified, approachable way to make baechu-kimchi that skips a few ingredients (like rice paste and salted shrimp) that many traditional recipes include. It makes about 1.5 lb (700 g) of kimchi, roughly 6 side-dish servings, and takes about 20 minutes of hands-on work, plus 1–2 hours of salting and at least a day to ferment.

What you’ll need:

• 1 medium napa cabbage (about 2 lb / 900 g), cut into bite-sized pieces
• 3 tablespoons coarse salt
• 3 tablespoons gochugaru (start here and add more to taste)
• 3 cloves garlic, minced
• 2 scallions, chopped
• 1–2 tablespoons fish sauce (aekjeot), to taste

Basic steps:

1. Toss the cut cabbage with the salt in a large bowl and let it sit for 1–2 hours, tossing once or twice. It’s ready when the pieces have visibly wilted and bend easily instead of snapping.
2. Rinse briefly under cold water to remove excess salt — taste a piece; it should be pleasantly salty, not overwhelming — then drain well for about 15 minutes.
3. Add the gochugaru, garlic, scallions, and fish sauce directly to the drained cabbage. Toss well with your hands (gloves recommended) until every piece is coated.
4. Taste and adjust the fish sauce or gochugaru until it’s seasoned the way you like.
5. Pack into a clean, airtight container, pressing down so the cabbage is covered by its own liquid.
6. Leave at room temperature for 1 day, then refrigerate. It’s ready to eat right away, and the flavor keeps developing over the next few days.

If you’d rather try the more traditional whole-cabbage method (pogi-kimchi), the process is similar but the cabbage is halved or quartered and salted whole in a saltwater brine for 2–3 hours instead of being cut and dry-salted, then the seasoning paste is spread by hand between each leaf rather than tossed through cut pieces. It takes longer and looks nicer, but the flavor principle is the same.

A First-Timer’s Guide to Gochugaru

Gochugaru (고추가루) is coarse, dried Korean chili flakes — generally less sharply hot than many Western chili flakes, with a fruitier flavor, and it’s what gives most kimchi its red color and heat.

If you’ve never cooked with it, start with less than a recipe calls for. It’s much easier to add more than to fix a batch that’s too spicy — cutting the amount by a third to a half makes a noticeable difference in heat without changing the rest of the flavor much.

Common Mistakes and Troubleshooting

• Tastes bland or watery. Usually under-salted, or rinsed too much after salting. Use the full salt amount and rinse more briefly next time.
• Tastes too salty. Rinse more thoroughly, or soak briefly in plain water before seasoning.
• Doesn’t taste sour after a week. Kept too cold, or the container isn’t airtight. Leave it at room temperature for the first day or two before refrigerating.
• Container looks fizzy or bulges. Normal fermentation gas — open the lid briefly once a day for the first few days to let it out.
• White, powdery film on the surface. This is kahm yeast, a harmless film that’s different from mold. Skim it off and make sure the kimchi stays fully submerged in its liquid to keep it from forming.
• Fuzzy, colored mold (black, green, pink). Not safe to eat — discard the batch. This usually means the kimchi wasn’t kept submerged or the container wasn’t clean.

Storage and Reheating

Kimchi keeps changing the whole time it’s in your fridge, which is expected rather than a sign it’s going bad. Fresh kimchi (a few days old) is mild and crunchy; well-fermented kimchi (1–4 weeks) is sourer and softer, which is what most people mean by “good kimchi”; older kimchi (a month or more) turns quite sour and soft and is best used in cooking rather than eaten raw.

Store it in an airtight container in the refrigerator, always keeping it submerged under its own liquid. It doesn’t need reheating on its own, since it’s eaten cold or at room temperature — it only gets “heated” when used as an ingredient in a cooked dish.

A Note on Allergens

Traditional kimchi contains fish (fish sauce) and often shellfish (salted shrimp). For a vegan version, leave both out and substitute soy sauce or a plant-based fish sauce alternative — this will change the traditional flavor somewhat, but the kimchi will still ferment and taste good.

Where to Buy Kimchi: Korean Market vs. Supermarket

If you’d rather not make kimchi yourself, buying it is completely normal — plenty of Korean households buy at least some of their kimchi too. A Korean grocery store will typically stock several kinds side by side — baechu-kimchi, kkakdugi, oi-sobagi, baek-kimchi — along with different fermentation levels, so you can pick based on how tangy you want it.

Something worth knowing before you judge kimchi by your first taste: small-packaged kimchi at mainstream U.S. grocery stores, including chains like Whole Foods, is often made or adjusted with a broader, less spice-tolerant customer in mind. Many of these products are milder, sweeter, and less fermented than what’s typically sold and eaten at Korean markets. That said, this isn’t true across the board — some brands sold in mainstream stores, including a few made by Korean-owned companies, are closer to what you’d find at a Korean market. It depends on the specific brand, so checking the ingredient list is more reliable than assuming based on where it’s sold.

If you’re curious what kimchi actually tastes like to most Koreans, a trip to a Korean market is worth making at least once to compare — even if it ends up being an occasional special-trip purchase rather than your everyday kimchi.

Frequently Asked Questions

Is kimchi vegan or vegetarian?
Usually not. Most traditional recipes include fish sauce and/or salted shrimp. Vegan versions exist and swap in soy sauce or a plant-based substitute instead.

Is pogi-kimchi different from mak-kimchi?
They’re the same basic kimchi, just cut differently — pogi-kimchi keeps whole or halved cabbage heads, while mak-kimchi is cut into bite-sized pieces first.

How long does kimchi last?
Properly refrigerated and kept submerged in its liquid, it typically lasts several weeks to a few months, growing more sour over time rather than spoiling outright.

Do I need to cook kimchi before eating it?
No. It’s designed to be eaten as-is, straight from the container.

Conclusion

Baechu-kimchi alone covers pogi- and mak-style, spicy and non-spicy, mild and sharply fermented — and that’s before getting into radish, cucumber, or the dozens of other types Korean cooks make. The easiest way to get a feel for it is to try a few kinds side by side, whether that’s a batch of quick homemade kimchi or a small container from a Korean market, and see what balance of sour, spicy, and salty you like best.
