Spicy Mushroom Sauce & Noodles

When mixed together, every strand of noodle is coated with umami savory spicy mushroom sauce. The mushroom gives this dish a nice bite and the Chinese green mustard stems provide a nice crunch.

The key to this dish is 'Lao Gan Ma' or Old Godmother chili sauce. Since there are more than one version, do source for the one with black beans. The black beans adds a level of umami flavor this saucy dish.

Also, do add a little bit of sesame oil towards the end for a hint of toasty and nutty flavor. Enjoy!

  • I used minced ginger from the Ginger People and sesame oil from La Tourangelle Artisan oils.

  • If you like this dish to be less spicy, omit the red chili pepper and replace it with red bell pepper.

  • Add a little bit of oil and salt to boiling water before blanching Chinese green mustard leaves. It only takes a minute or two to blanch the greens.
