Hi, James Anderson and Yukiko here, your culinary guide at Food And Meal. Today, I’m happy to share with you a topic that’s close to my heart and palate – homemade wasabi. Yes, you heard it right! We’re diving into the world of this fiery green paste that has the power to transform any dish from ordinary to extraordinary.

As a chef, I’ve always been fascinated by the unique flavor profile of wasabi. It’s not just about the heat; it’s about the subtle, earthy undertones that can add depth to a variety of dishes. From sushi to steak, wasabi has a way of elevating the taste experience to a whole new level.

But let’s be honest, most of us are familiar with the store-bought version, which often contains European horseradish and green food coloring. While it does the job, nothing beats the authentic taste of homemade wasabi, made from the Japanese horseradish plant, Wasabia japonica. The difference in flavor is like night and day!

In this post, I’ll be sharing some of my favorite recipes that incorporate homemade wasabi. These recipes are not only delicious but also a fun way to experiment with this versatile ingredient. Whether you’re a seasoned cook or a beginner in the kitchen, I promise these recipes will bring a dash of adventure to your cooking routine.

So, are you ready to turn up the heat in your kitchen? Let’s dive into the exciting world of homemade wasabi!

Best Wasabi Recipes

If you’re wondering how to make wasabi easily, this recipe is perfect for you. Preparation is very critical. It’s important to make sure that the wasabi recipe you use is fresh and made from the right ingredients. It should be stored in an airtight container, preferably in a cool place. In addition to that, the wasabi paste can also be molded. Once it’s ready to use, place it on a dish.

Wasabi ingredients – What will you need ?

To prepare fresh wasabi, one would need the following:

  1. Wasabia japonica rhizome: This is the main component of wasabi. It is often difficult to find outside Japan as it requires specific growing conditions, but it can sometimes be sourced from specialty stores or online suppliers.
  2. Grater: A traditional sharkskin grater, known as an oroshigane, is used to grate the wasabi rhizome into a fine paste. However, a fine metal grater can also be used as a substitute.
  3. Water: A small amount of water may be mixed with the grated wasabi to adjust its consistency.

For those who do not have access to fresh Wasabia japonica, a common alternative is a wasabi paste made from a combination of horseradish, mustard, starch, and green food coloring. This is widely available in tubes or as a powder that can be reconstituted with water. In our recipe, the wasabi ingredients:

  1. Horseradish
  2. Mustard powder
  3. Soysauce
  4. Vinegas
  5. Anchovy

It’s important to note that the flavor profile and potency of fresh Wasabi japonica differ significantly from the horseradish-based substitutes. Fresh wasabi has a more delicate, herbal, and nuanced taste compared to the sharper and more robust flavor of horseradish.


Homemade Wasabi Recipe: A Step-By-Step Guide 1


The wasabi recipe can be used to make sauces or dips. It is very spicy, so it's best to keep it refrigerated. However, if you plan to serve it to others, you can grate the rhizome into a ball and serve it in a sculpted form. As long as it's stored in a container that's air-tight, it will stay fresh for a long time.

From the rhizome

  • Wasabi root

From horseradish (imitation wasabi)

  • 4 teaspoons horseradish grated
  • 1 teaspoon Chinese mustard pounded or pureed
  • A few drops Soy sauce according to taste
  • A few drops vinegar to taste (enhances pungency)
  • 1 cooked anchovy chopped finely (optional)


From the fresh rhizome

  • Wash the wasabi rhizome and let it air dry.
  • Peel about ⅓ inch around the end.
  • Grate using a fine grater, or special wasabi sharkskin grater, enough for 1 serving or more.
  • Shape the resulting paste into a ball and let it stand for about 10 minutes for the flavor to develop.
  • Wrap any leftover in a damp paper towel and then with plastic wrap.
  • Note: Wasabi is pungent, so be careful not to get it in your eyes. Also, the flavor quickly deteriorates.

To store wasabi root

  • Wrap it in muslin cloth, leaving the cut end exposed.
  • Immerse the cut end in a little water and refrigerate. Change the water every 3 days. Wasabi will keep this way for about a month.

To make imitation wasabi

  • Combine ingredients thoroughly and adjust the flavor accordingly. Store in an airtight jar and refrigerate.
  • A regular condiment for sushi.



  • Wasabi's intensity can vary based on its preparation. Always taste and adjust according to your preference. Remember, it's easier to add more than to take away.
  • While wasabi is traditionally paired with sushi, its versatile nature allows it to be used in various dishes. Be adventurous and let your culinary imagination soar.
  • For those new to wasabi, the heat might be intense initially but quickly mellows. Don't be put off by the initial punch; the nuanced flavors are worth the journey.

Wasabi Ingredients:

  • 1 fresh wasabi rhizome (about 2-3 inches)
  • 1 teaspoon of water
  • 1/4 teaspoon of sugar
  • A pinch of salt


  • Prep the Wasabi: Begin by peeling the fresh wasabi rhizome using a knife or a vegetable peeler to remove any outer skin. Cut it into small, manageable pieces.
  • Add Sugar and Salt: In a small bowl, combine the sugar and a pinch of salt. Sprinkle this mixture over the pieces of wasabi and let them sit for about 5 minutes. This will help release the flavors.
  • Blending Process: Place the wasabi pieces into your food processor. Add about a teaspoon of water to aid in the blending process.
  • Pulse and Scrape: Pulse the food processor a few times, then stop to scrape down the sides. Repeat this process until the wasabi is finely grated. Be cautious not to over-process, as this can heat the wasabi and reduce its spiciness.
  • Taste and Adjust: Taste your homemade wasabi and adjust the spiciness to your liking by adding more grated wasabi or a pinch of sugar if needed.
  • Transfer and Store: Transfer your freshly made wasabi paste to an airtight container. Store it in the refrigerator for up to a week.

Tips for making Wasabi

A dash of homemade wasabi – fiery perfection.

Cooking Tips

  • Choosing the Right Rhizome: Select a fresh wasabi rhizome that feels firm and heavy. Avoid any that appear shriveled or dry. The best rhizomes are often vibrant green and have a clean, earthy aroma.
  • Peeling and Prepping: When peeling the rhizome, use a knife or vegetable peeler to remove the outer skin. Cut it into small pieces for easy blending or grating.
  • Grating or Blending: Whether you choose to grate by hand or use a food processor, be cautious not to over-process. Overheating can reduce the spiciness of wasabi. Aim for a fine, paste-like consistency.
  • Sugar and Salt Trick: Enhance the flavor by combining the wasabi pieces with a pinch of sugar and salt for a few minutes before blending or grating. This brings out the natural heat and aroma.
  • Maintain Freshness: To maintain the freshness and vibrant green color of your homemade wasabi, store it in an airtight container in the refrigerator. Keep it away from air and light exposure.
