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
Use only half the chile rings for a milder soup - you can always add more heat but can't take it away.
Weight the dried mushrooms with a small cup or plate to keep them fully submerged for even rehydration.
Don't overcook the fresh mushrooms in step 3 - they should still have some bite since they'll continue cooking in the broth.
Good to Know
Refrigerate leftovers up to 3 days. Reheat gently to avoid overcooking mushrooms.
Can prep ingredients up to 1 day ahead. Assemble and cook just before serving for best texture.
Serve immediately in warm bowls while hot. Pairs well with steamed rice or Asian dumplings.
Common Mistakes
Don't skip weighing down the dried mushrooms or they'll float and rehydrate unevenly.
Avoid overcooking fresh mushrooms in the aromatics step to prevent them becoming mushy.
