Kochujang is made of red pepper paste. It is a very thick spicy paste which is slightly sweet. It's another staple condiment present in almost every spicy Korean food. It also serves as a thickener in some sauces. While we Pinoys enjoy spicy food, this particular spice however is a whole new level of hotness.
This product is a little pricey, but if you get the refill pack you can save half the price.
