Being gentle, trim away about 1-inch of the root section from the mushrooms. Next, use your fingers to tear the enoki mushrooms into small bite-sized bundles.
Prepare a wok or skillet with boiling water, and carefully blanch the enoki mushrooms for 1 minute. Remove and drain on paper towels then line them up on a small serving plate.
Heat the vegetable oil and sesame oil in a small saucepan over medium heat. Add the garlic and cook, stirring constantly, for 10 seconds.
Add the soy sauce, scallions, sugar, and sriracha. Bring to a boil and turn off the heat. Don't overcook. the garlic and scallions--you want them to taste fresh and sweet not bitter.
Slowly pour the well-whisked sauce over the enoki mushrooms and serve. Enjoy.
