Gochugaru is not just any chilli flake. Korean chilli flakes are smoky, slightly sweet, and vibrant red — essential for kimchi, tteokbokki, and dozens of other dishes. Here are four options available in the UK.
Why Gochugaru Is Not Regular Chilli Flakes
If you try to make kimchi with standard supermarket chilli flakes, the results will be disappointing. Gochugaru is a specific product made from Korean red peppers (taeyangcho) that are sun-dried and ground to various textures. The flavour profile is markedly different from Italian peperoncino or generic chilli flakes — gochugaru is fruity, slightly smoky, mildly sweet, and has a gentle, building heat rather than an immediate sharp burn. The colour is a vivid, almost luminous red that gives kimchi and Korean stews their characteristic hue.
Coarse vs Fine
Gochugaru comes in two main grinds and they serve different purposes. Coarse flakes (gulgeun gochugaru) are used for making kimchi — the rough texture clings to the cabbage leaves and creates the right visual effect. Fine powder (gorun gochugaru) is used in stews, marinades, and sauces where you want the chilli to dissolve into the liquid. Many Korean cooks keep both on hand. If you can only buy one, start with coarse — you can use it for most applications and blitz it in a spice grinder when you need powder.
The Picks
**CJ Haechandle Coarse Gochugaru** is the most widely available option in the UK and produces reliable results for kimchi. The colour and flavour are good, though at 200g the packet is small for the price. **Sempio Fine Powder** is the best option for stews and sauces — it dissolves smoothly and has a well-balanced heat. **Chung Jung One Sun-Dried** is a step up in quality — the sun-drying produces a more complex, slightly smoky flavour. The 500g bag offers better value per gram. **Taekyung Premium** is the one to seek out if you are serious about kimchi making — it has the deepest colour, most complex flavour, and most authentic aroma of the four.
Storage Matters
Gochugaru degrades quickly when exposed to air, light, and heat. The vibrant red colour fades to brown and the flavour flattens. Store opened gochugaru in an airtight container in the freezer — it will keep its colour and potency for up to a year. At room temperature, it begins losing quality within a few weeks. This is one ingredient where buying a larger bag and freezing it makes significantly more sense than buying small packets as needed.
