Have you guys ever made hot and sour soup?
It's basically water, chicken broth + red vinegar OR white rice vinegar OR red wine vinegar or regular vinegar (the least desired option since it's so strong with a dull flavour) + any kind of hot sauce or chili oil.
Throw in sliced mushrooms, tofu, bamboo shoots and meat (optional).
You boil the shit out of it, stir in cornstarch and water to thicken.
That's a simple version. If you want to jazz it up, add soy sauce, sesame oil, fungus, lily buds, slice your bamboo shoots, ground pork bits, pork tenderloin slices, green onion, ginger bits if you're sick....
