Gochugaru vs Gochujang: What’s the Difference?

If you’ve ever cooked Korean food  or even just explored bold Asian flavours you’ve probably come across gochugaru and gochujang.

They sound similar. They look related. But they play very different roles in cooking.

Understanding the difference between the two is the key to getting that deep, balanced Korean flavour right.

What Is Gochugaru?

Gochugaru is a type of Korean chilli flake made from sun-dried red peppers.

It’s known for its:

  • Bright red colour

  • Mild-to-moderate heat

  • Slight sweetness

  • Smoky, earthy depth

Rather than being aggressively spicy, gochugaru is about warmth and flavour.

It’s commonly used in:

  • Kimchi

  • Soups and stews

  • Marinades

  • Seasoning blends

What Is Gochujang?

Gochujang is a thick, fermented Korean chilli paste.

It’s made from:

  • Chilli powder (often gochugaru)

  • Fermented soybeans

  • Glutinous rice

  • Salt

The result is a paste that’s:

  • Sweet

  • Savoury

  • Spicy

  • Deeply umami-rich

It’s often used in:

  • Bibimbap

  • Sauces and glazes

  • Stir-fries

  • Dipping sauces

The Key Difference

The simplest way to think about it:

  • Gochugaru = spice (dry, flexible, flavour-building)

  • Gochujang = sauce base (thick, fermented, complex)

One builds flavour gradually. The other delivers a complete flavour in one spoon.

Can You Use Gochujang Instead of Gochugaru?

Not directly. While both contain chilli, they behave very differently:

  • Gochugaru adds dry heat and colour

  • Gochujang adds sweetness, saltiness, and moisture

If you substitute gochujang for gochugaru, your dish may become:

  • Sweeter

  • Heavier

  • More sauce-like

If you do swap: Use a small amount of gochujang and adjust other ingredients (reduce sugar, salt, and liquids).

What Can I Replace Gochugaru With?

If you don’t have gochugaru, you can try:

  • Mild chilli flakes (closest substitute)

  • Paprika + a pinch of cayenne (for colour + heat)

  • Aleppo pepper (similar mild warmth)

But keep in mind, gochugaru has a unique balance of sweetness and smokiness, so substitutes won’t be identical.

Does Kimchi Use Gochujang or Gochugaru?

Traditional kimchi uses gochugaru, not gochujang.

Gochugaru gives kimchi:

  • Its signature red colour

  • A clean, layered heat

  • Room for fermentation flavours to develop

Gochujang is sometimes added in modern variations, but it’s not the traditional base.

Where Umei Fits In

At Umei, we love gochugaru for its ability to bring warmth without overpowering heat.

Our Umei Gochugaru Mayo is inspired by this balance combining creamy Japanese-style mayo with the gentle heat and depth of Korean chilli.

It’s not about making things spicy. It’s about making them more interesting.

Which One Should You Use?

  • Dry seasoning

  • Layered heat

  • Control over flavour

Use gochujang when you want:

  • A ready-made flavour base

  • Sweet + savoury + spicy in one

  • A thicker sauce or glaze

Both have their place and often, they work best together.
