What Exactly Goes Into Gochujang? (Ingredients for a 1-Year Supply)
Before we jump into the kitchen, let’s talk about quantity. A typical Korean family of four uses about 10 to 12 kilograms of Gochujang a year. This might sound like a lot, but when you put it in stews, marinades, and dipping sauces every week, it disappears faster than you think!
To make this amount, you do not need any crazy chemicals. Traditional Gochujang relies entirely on natural fermentation. Here are the five main ingredients you will need:
- Gochutgaru (Korean Red Chili Pepper Powder): You need about 3 kg. Make sure to get the finely ground type, not the coarse flakes used for Kimchi. This gives the paste its beautiful smooth texture and vibrant red color.
- Mejutgaru (Fermented Soybean Powder): You need around 1 kg. This is the secret source of that deep, savory “umami” flavor. It is the same base used to make Korean soy sauce.
- Yeotgireum (Barley Malt Powder): You need about 1.5 kg. This is used to create a sweet liquid base that helps break down the starches.
- Grain Base (Rice Syrup or Glutinous Rice): You will need about 3 to 4 kg of rice syrup (or you can boil down sweet rice flour). This adds that signature sticky texture and subtle sweetness.
- Sea Salt: You need about 1 kg of coarse Korean sea salt. Salt keeps the paste safe from bad bacteria while it ferments.
The Step-by-Step Process: How the Magic Happens
Making Gochujang is actually more about patience than complicated cooking skills. Think of it like a fun weekend science project. Here is how you do it, step by step.
Step 1: Making the Sweet Barley Malt Water
First, we need to extract the sweet goodness from the barley malt powder. Mix the powder with warm water, let it sit for a few hours so the flavors settle, and then strain out the solids using a fine cloth. Take that clear liquid and simmer it in a large pot for a few hours. If you are using sweet rice flour, this is the time to mix it in and let it dissolve until the liquid becomes sweet and slightly thick.
Step 2: The Big Mix
Let the hot liquid cool down until it is just warm to the touch. This part is super important! If the liquid is too hot, it will kill the good microbes in our soybean powder. Once it is warm, stir in the fermented soybean powder until there are no lumps. Next, add your smooth red chili powder and the salt. Give it a really good stir. It will start looking like the thick, shiny red paste we all love.
Step 3: Aging and Fermentation
Now, pour the paste into a large earthenware jar, known as an Onggi in Korea. If you do not have one, a large glass jar works too. Cover the top with a breathable cloth and secure it with a rubber band. Now comes the waiting game. Place the jar in a sunny, well-ventilated spot like a balcony or a backyard. Let it ferment for at least 2 to 3 months. The sun will do all the hard work, deepening the color and smoothing out the sharp edges of the chili and salt.
A Few Simple Tips for Beginners
If you are trying this for the first time, do not worry! Here are two quick tips to keep in mind. First, always make Gochujang during the cooler months, like late autumn or early spring. If it is too hot outside, the paste can spoil before it ferments correctly. Second, make sure all your utensils and jars are perfectly clean and dry. Water is the enemy during the early stages of fermentation.
Once your Gochujang is aged, you can store it in the fridge to stop the fermentation process, and it will stay good for years. You will be so proud to tell your friends that the amazing spicy kick in your dinner came straight from your own homemade batch!
