Vegetarian Hot & Sour Soup with Shiitake Mushrooms

This aromatic soup balances spicy heat from red finger chiles with tangy Chinese black rice vinegar for an authentic hot and sour flavor profile. Dried and fresh shiitake mushrooms provide deep umami richness, while red bell peppers add sweetness and color. The soup simmers briefly to meld the flavors while keeping the mushrooms tender but not overcooked. Perfect as a warming appetizer for Asian meals or a light lunch on cool days.

Tips

Tip 1

Use only half the chile rings for a milder soup - you can always add more heat but can't take it away.

Tip 2

Weight the dried mushrooms with a small cup or plate to keep them fully submerged for even rehydration.

Tip 3

Don't overcook the fresh mushrooms in step 3 - they should still have some bite since they'll continue cooking in the broth.

FAQ

Can I make this soup less spicy?

Yes, use only half the chile rings or remove the seeds before slicing. You can also substitute with milder peppers like jalapeño.

What if I can't find Chinese black rice vinegar?

Regular rice vinegar works as a substitute, though the flavor will be milder and less complex than traditional black vinegar.

How long will leftovers keep?
