Once you have your fresh wasabi, it’s essential to store it properly until you’re ready to use it. Wrap it in a damp paper towel and store it in an airtight container in the refrigerator. When you're ready to prepare the paste, remove the wasabi root from the refrigerator and allow it to come to room temperature for about 30 to 45 minutes.
Using a fine grater, grate the wasabi root into a fine paste. It's advisable to use a traditional sharkskin grater for the best texture, but a ceramic or stainless steel grater will work fine as well.
Once the wasabi has been grated into a fine paste, transfer it to a small bowl. Gradually add water, a teaspoon at a time, mixing well after each addition, until you reach your desired consistency. Some prefer a thicker paste, while others may want a slightly looser consistency.
Wasabi, also known as Japanese horseradish, is a root vegetable that belongs to the Brassicaceae family, which also includes mustard, horseradish, and cabbage. It is traditionally grown along stream beds in mountain river valleys in Japan. Due to its unique taste and health benefits, wasabi has been a staple in Japanese cuisine for centuries. The part of the plant used is the stem or rhizome which, when grated, turns into a spicy paste that is commonly used as a condiment for sushi and sashimi.
Wasabi has a distinct, sharp, pungent flavor that provides a quick, intense heat followed by a sweet, mild aftertaste. Unlike the lingering burn you get from chili peppers, the spiciness of wasabi is more akin to a burst of horseradish heat that hits the nose more than the tongue. Its complex flavor profile adds a unique zest that can elevate the taste of many dishes, making it a cherished ingredient in various culinary applications beyond its traditional use.
