Korean dried chilli flakes — fruity rather than fiercely hot.
Gochugaru is the soul of Korean cooking — sun-dried red chilli ground into vivid flakes that give the cuisine its glowing colour and its signature warm, fruity heat. It seasons everything from the fermented heart of kimchi to bubbling stews and grilled-meat marinades. What sets it apart from other chilli powders is its clean, sweet-edged flavour and its moderate heat, which lets it be used by the tablespoon rather than the pinch.
Made from Korean red peppers that are dried, de-seeded and crushed, gochugaru carries a layered flavour: a fruity sweetness, a faint smokiness, and a heat that builds gently rather than biting. Because the seeds are removed, the burn stays clean and the colour is a deep, true red. It comes in two grades — coarse flakes for kimchi, where texture matters, and a fine powder for smooth sauces and seasoning blends. The same chilli is the basis of gochujang paste, so the two share a family resemblance on the palate. That fruity backbone is also why gochugaru reads as savoury rather than merely hot, sitting comfortably alongside garlic, soy and fermented flavours instead of fighting them.
Gochugaru needs no toasting or grinding; it is ready to use straight from the bag. For kimchi it is mixed with garlic, ginger and fish sauce into a paste that coats the vegetables. In stews it is often bloomed first in a little oil with garlic to deepen its colour and release the aroma before liquid is added, a step that rounds out the flavour. As a finishing seasoning it can simply be sprinkled in. Because brands differ in heat, add it in stages and taste, building the warmth gradually rather than committing it all at once.
Choose flakes that are bright, deep red and slightly tacky to the touch, with a fresh, fruity smell; dull, dusty or brownish gochugaru has oxidised and lost its punch. Buy from a source that turns over stock quickly. Once opened, seal it tightly and keep it cool and dark, or store it in the fridge or freezer to lock in colour and aroma for many months. Coarse and fine grades are not always interchangeable, so check which a recipe wants before buying.
Gochugaru is the defining heat in kimchi jjigae and gives the glossy red sauce of tteokbokki its character. It also seasons the spicy version of Korean fried chicken coatings and glazes. If none is available, a blend of sweet paprika and a little cayenne approximates the colour and mild warmth, though it misses the fruity sweetness.

Gochugaru is Korean red chilli, sun-dried and then ground or crushed into flakes. It is the backbone seasoning of Korean cooking, giving dishes their characteristic warm red colour and gentle, fruity heat. Unlike many chilli powders it is made without seeds or added oils, so it has a clean, bright flavour. It comes in two main textures: a coarse flake for kimchi and stews, and a finer powder used where a smoother result is wanted, such as sauces and marinades.
It is moderate rather than fierce — noticeably milder than cayenne or Thai bird chilli. Its heat is rounded and slow to build, balanced by a distinct fruity, slightly smoky sweetness, which is why it can be used generously to colour and flavour a dish without overwhelming it. Heat does vary between brands and harvests, so it is wise to taste a pinch and adjust. The goal in most Korean dishes is a glowing red warmth, not searing spice.
Not cleanly, since gochugaru is milder and fruitier than European crushed chilli, which is often hotter and contains seeds. A workable approximation is to blend sweet paprika with a smaller amount of cayenne or hot chilli flakes, aiming for colour and mild warmth rather than sharp heat. The result will lack gochugaru's particular sweetness but will serve in a pinch. For kimchi and signature stews, though, the real thing makes a clear difference.
Like all ground chilli it fades with light, heat and air. Keep it sealed in an airtight container in a cool, dark cupboard, where it holds its colour and flavour for several months. For longer keeping, many cooks store it in the fridge or freezer, which preserves the bright red hue and fruity aroma especially well. If the flakes turn dull brown or smell flat, the heat and flavour have gone and a fresh bag is due.
