Learn more about konjac noodles

Konjac noodles, also called shirataki or konnyaku, are made from the konjac root, a plant native to the tropical and subtropical regions of East and Southeast Asia, particularly Vietnam, China, India, Indonesia, and Japan.

This root is ground into flour (or konjac powder), then mixed with water and a little calcium (often in the form of calcium hydroxide) to create a gelatinous dough.

This dough is then extruded or molded to create different shapes: vermicelli, tagliatelle, or even shapes resembling classic pasta or rice. The result is a Japanese product that is very low in calories, gluten-free, and sugar-free, often used in Japanese dishes, miso soups, tofu recipes, or stir-fried with soy or sesame sauces.

Their flavor is neutral, slightly earthy or briny if they are not rinsed properly, as they are preserved in calcium-rich storage water.

But that is precisely what makes them so interesting in Japanese cuisine: they absorb sauces, miso broths, soy sauce, and seasonings such as sesame, ginger, or dashi perfectly. Their slightly elastic texture is reminiscent of rice vermicelli or Asian translucent noodles.

The classic Japanese dressing, ideal for accompanying konjac noodles, shirataki noodles, tofu salads, or cold dishes, is a light, tangy sauce rich in umami. It is made with simple and flavorful Japanese ingredients.

Ingredients:

Preparation:

  • Mix all the ingredients in a bowl or small shaker.
  • Whisk well until the miso has dissolved (if using).
  • Taste and adjust: add more sugar for sweetness or more vinegar for acidity.

Konjac, especially shirataki noodles, can be used in many flavorful, low-calorie Japanese hot dishes. Thanks to its ability to absorb flavors, it is an excellent substitute for traditional pasta or noodles in classic or modern recipes.
