Korean Pantry Essentials: The 8 Bottles That Actually Run My Seoul Kitchen

This post contains affiliate links. As an Amazon Associate I earn from qualifying purchases — and this list is my actual pantry, not a brand catalog.

Ask the internet "what do I need to cook Korean food?" and you'll get the same answer every time: gochujang, gochujang, gochujang.

So let me tell you a small secret from an actual Korean kitchen — mine, in Seoul, where I cook between lessons and rehearsals: the red pastes are the celebrities, but the brown liquids do all the work.

The jars you've heard of come out once a week. The bottles you've never heard of come out every single day. This is the honest version of a Korean starter pantry — the eight things that actually run my kitchen, plus one free trick that isn't a product at all.

Quick Verdict

> What actually runs a Korean kitchen isn't the famous red pastes — it's a handful of brown umami liquids you've never heard of.
 > MVP: tuna aekjeot (참치액). One spoon rescues any flat soup or stew — and, my confession, a whole pan of pasta.
 > The one Westerners always miss: soup soy sauce (국간장). Seasons soups and namul without darkening them.
 > Free trick: rice water (쌀뜨물) from rinsing rice = my default soup base. Costs nothing.
 > If you only buy three: tuna aekjeot, soup soy sauce, low-sugar gochujang. Korean flavor isn't spicy first — it's deep first.

My actual lineup.
The tall red bottle is the one I'd save from a fire
— more on that in a second.

Part 1: The Umami Liquids (The Real Engine)

1. Tuna aekjeot (참치액) — the bottle I'd rescue from a fire

If I could only keep one thing on this list, it's this. Chamchi-aek is a savory seasoning sauce made from tuna — think of it as fish sauce's rounder, deeper Korean cousin. A spoonful finishes a soup, seasons a stew, and fixes almost anything that tastes "flat."

And here's my confession, which I've never seen on any Western food blog: I season my pasta with it. When an aglio e olio tastes fine but not alive, tuna aekjeot instead of more salt — one to two spoons for a big pan (I always cook a big pan), half a spoon if you're cooking for one — and the umami goes three floors deeper. Nobody can ever name what changed. My Korean-Italian secret, now yours.

Yes, I put tuna sauce on my pasta.
No, I won't apologize. Try it once and you'll get it.

I rotate between brands at home — Koreans rarely stay loyal to one — and the one you can actually get on Amazon is Sajo's Tuna Katsuo Sauce, a solid, standard bottle of the real thing.

2. Soup soy sauce (국간장) — the one Western recipes always miss

Korean kitchens run on two different soy sauces, and this is the one foreigners never buy. Guk-ganjang is lighter in color but saltier and deeper — it seasons soups and namul without darkening them. If you've ever made a Korean soup recipe with regular soy sauce and wondered why it tasted vaguely wrong: this is why. Sempio's soup soy sauce is the standard bottle.

3. Zero-sugar oyster sauce — the kick

My wildcard. A squeeze of Vivid Kitchen's zero-sugar oyster sauce is what turns kimchi fried rice from "good" into why is this so good — and yes, it sneaks into pasta too. I use the zero-sugar version because most oyster sauces are quietly loaded with sugar, and this one keeps the punch without it.

Part 2: The Broth Department

The unglamorous heroes: broth coins and soup soy sauce.
These outwork every red paste in my kitchen.

4. Broth coins (육수코인) — cheating, officially sanctioned

Real Korean soup starts with anchovy-kelp broth, and nobody busy makes it from scratch on a Tuesday. Enter broth coins: drop one tablet in water, simmer, done — honest anchovy depth in five minutes. These anchovy broth tablets are the category standard on Amazon.

(A preview of where this is going: these coins plus the soup soy sauce above are the entire seasoning backbone of my favorite high-protein, absurdly cheap Korean soup — hwangtae-guk, dried pollack soup. That recipe gets its own post soon.)

5. The free one: rice water (쌀뜨물)

Here's the trick no one can sell you. When you rinse rice, keep the cloudy water from the second rinse — that's ssal-tteumul, and it's my default soup base. It adds body and a gentle roundness to doenjang stew that plain water never gives. Cost: zero. This is the most Korean-grandmother move in this entire post.

Don't pour this out.
Cloudy rice water is my free soup base
— the most grandmother thing I do

Part 3: The Pastes (Yes, Fine, the Famous Ones)

6 & 7. Gochujang and ssamjang — but hear me out: low-sugar

Of course you need them. But here's what surprised even my Korean friends: standard gochujang is nearly a third sugar. I switched to Thank-you's sugar-free gochujang (sweetened with allulose) and their sugar-free ssamjang a while ago, and honestly? The flavor holds. Heat, depth, that fermented low hum — all there, minus the sugar crash. Same bottles I have at home right now.

8. Doenjang — for the stew that tastes like Korea

Fermented soybean paste, the soul of doenjang-jjigae — which, made with rice water from tip #5 and a broth coin from tip #4, is the single most comforting thing this pantry produces. Haechandle Soybean Paste (Korean Doenjang) is a standard, widely available choice, and it keeps for months in the frige. 

The Finisher

Sesame oil (참기름) — the last three seconds of every dish

You knew this was coming. One teaspoon, added after the heat is off, and suddenly everything smells like a Korean home. Mine comes from a neighborhood oil mill in Seoul — a bangatgan, where they roast and press the seeds while you wait — but Ottogi's roasted sesame oil is the yellow-capped standard that Korean kitchens everywhere run on. (I wrote a whole love letter to Korean sesame and perilla oils here, if you want the deep dive.)

What About Gochugaru, Kimchi, All the Rest?

Fair question. Gochugaru — Korean chili flakes — is actually Amazon's biggest Korean pantry bestseller (the Taekyung bag has almost fifteen thousand reviews, mostly from brave souls making kimchi at home). I left it off my core list only because my own cooking leans on the bottles above far more than on loose chili flakes. If kimchi-making is in your future, add it to the cart.

If You Only Buy Three

Start here: tuna aekjeot, soup soy sauce, low-sugar gochujang. With those three and the rice-water trick, you can cook a shockingly convincing Korean dinner tonight — and you'll understand something most starter guides never teach: Korean flavor isn't spicy first. It's deep first.

For what I actually cook with all this on a normal week, my anti-aging diet post is the companion piece.

Which bottle surprised you most? And if you try the pasta trick — report back. I need witnesses.
