Combine garlic, scallion, sesame seeds, chili flakes, Sichuan peppercorns, white pepper into a bowl
Heat up oil in a small pot
Once the oil is starting to smoke, take it off the heat, then pour over the aromatics
Once it's stopped bubbling, add in soy sauce, oyster sauce, black Chinese vinegar and sugar. The sauce is done
Boil some water, add in your veggies, potato noodles and thinly sliced beef. Cook for about 2 minutes, remove any scum on top. Potato noodles should still have a bite to it.
Add some the water from the pot into your noodle bowl with your sauce.
Put the potato noodles, veggies and beef brisket into the bowl.
Top off with some cilantro and peanuts (optional). Enjoy!
