Making Homemade Cambodian Prahok with Readily Available Ingredients

Cambodian cuisine is renowned for its bold flavors and rich heritage, and one of its most iconic ingredients is prahok. Prahok is a fermented fish paste that adds a unique umami punch to many traditional dishes. While making prahok might seem daunting, it's quite feasible with ingredients available at your local supermarket. Let's dive into how you can create this essential Cambodian ingredient right in your kitchen.

Ingredients You'll Need

To make homemade prahok, you'll need the following ingredients:

  • Fresh Fish: Use a fish that’s readily available and affordable. Herring, mackerel, or sardines are great options due to their oily nature, which helps in the fermentation process.
  • Salt: A critical component for fermentation. Make sure to use coarse sea salt or kosher salt.
  • Rice Wine or White Vinegar: To aid in the fermentation process and add a slight tang.
  • Garlic (optional): Some variations include garlic for added flavor.


  • Glass or Ceramic Jar: For fermenting the fish. Avoid metal containers as they can react with the fermentation process.
  • Cheesecloth or Clean Cloth: To cover the jar and allow it to breathe while keeping contaminants out.
  • Sharp Knife and Cutting Board: For cleaning and filleting the fish.
  • Mixing Bowl: For combining the fish and salt.

Step-by-Step Guide

1. Prepare the Fish

Start by cleaning and gutting your fish. Remove the heads and bones if desired, though keeping them can add to the flavor. Fillet the fish and cut it into small, bite-sized pieces.

2. Salt the Fish

In a mixing bowl, generously coat the fish pieces with salt. The rule of thumb is to use about 15-20% of the fish’s weight in salt. This not only helps preserve the fish but also aids in the fermentation process.

3. Pack the Jar

Place the salted fish pieces into your glass or ceramic jar. Pack them tightly to minimize air pockets, which can lead to spoilage.

4. Add Rice Wine or Vinegar

Pour a small amount of rice wine or white vinegar over the fish. This helps to kickstart the fermentation and adds a slight tangy flavor to the prahok.

5. Cover and Store

Cover the jar with cheesecloth or a clean cloth. Secure it with a rubber band or string to keep it in place. Store the jar in a cool, dark place. The ideal temperature is around 60-70°F (15-21°C). Avoid direct sunlight, as it can negatively affect the fermentation process.

6. Fermentation Process

Allow the fish to ferment for at least a month. The longer it ferments, the stronger the flavor will be. Some traditional recipes call for up to six months of fermentation. Check on the prahok occasionally to ensure it’s fermenting correctly. You should notice a distinct, pungent aroma as it ferments.

7. Final Product

After the desired fermentation period, your prahok is ready to use. Transfer it to smaller jars for storage. Prahok can be stored in the refrigerator for up to a year, retaining its bold flavor and aroma.

Storing Your Prahok

Proper storage is key to maintaining the quality and flavor of your homemade prahok:

  • Refrigeration: Store the prahok in an airtight container in the refrigerator. This helps preserve its freshness and prevent any unwanted bacterial growth.
  • Freezing: For longer storage, prahok can be frozen. Divide it into small portions, place in airtight containers or freezer bags, and freeze. This way, you can thaw only what you need for a specific recipe.
  • Labeling: Always label your containers with the date of preparation. This will help you keep track of how long the prahok has been stored.

Using Your Homemade Prahok

Prahok is a versatile ingredient in Cambodian cuisine. Here are a few ways to use it:

  • In Sauces and Dips: Mix prahok with lime juice, garlic, chili, and sugar for a flavorful dip or sauce.
  • In Soups and Stews: Add a spoonful of prahok to enhance the umami depth of soups and stews.
  • With Vegetables: Stir-fry vegetables with prahok for a savory and aromatic side dish.

Final Tips

  • Be Patient: Fermentation is a slow process, but the result is worth the wait.
  • Experiment: Feel free to experiment with the amount of salt and fermentation time to find your preferred flavor profile.
  • Stay Clean: Ensure all utensils and containers are thoroughly cleaned to prevent contamination.

Making prahok at home is a rewarding process that connects you to the rich culinary traditions of Cambodia. Enjoy your homemade prahok and the depth of flavor it brings to your dishes!
