Fine gochugaru is powder-like and available at Korean markets or online. Alternatively, you can press coarse gochugaru through a fine-mesh sieve or grind it in a spice grinder. We’ve added pork belly to enhance the flavor, but it can also be left out to make a meatless version. Store-bought kimchi may not be fully ripe when you bring it home. To ripen it further, ommend that you open it and allow it to sit covered in the refrigerator for up to a week to continue fermenting and ripening for the best flavor in this stew.
