Gochujang is a traditional Korean fermented chilli paste with a deep, savoury heat. Authentic versions can vary quite a lot in spice level depending on the brand, so it’s always best to start with a smaller amount and adjust to your preference. If using a supermarket brand, you may need to use more typically. In this recipe, the quantity used gives warmth and depth rather than strong heat. If you’re new to gochujang or unsure of your brand’s spice level, begin with slightly less and taste before adding more. You can always increase it to suit your desired level of heat.
