Add some acid to remove the unpleasant smell. I usually go for lemon juice, but lime juice, apple cider vinegar, or white vinegar all work too. Add about 1 teaspoon to a single serve package of shirataki noodles; add about 1 tablespoon to a family size package of shirataki noodles. Toss with your hand to coat all the noodles with the acid. Allow to rest in the acid for about 2 minutes.
