Session 161 — Hot and Sour Soup (酸辣汤)
← Block 33–34: Chinese Cuisine Overview
Skill: Hot and sour soup is the Chinese umami bomb — built on a well-made pork stock (or chicken stock), with the interplay of acid (black vinegar), heat (white pepper + chilli), and texture (wood ear mushrooms, silken tofu, egg ribbons). The egg ribbon technique — pouring beaten egg in a thin stream into simmering soup while stirring — produces the characteristic feathery strands.

The thickening and egg ribbon technique: 1. Cornstarch slurry added to simmering stock thickens to a loose, viscous consistency 2. Egg: beat until uniform; hold over the pot; pour in a thin stream while stirring the soup in a circular motion with the other hand 3. The motion creates ribbons rather than clumps — the circular current spreads the egg before it sets
Full Meal: Hot and sour soup as a complete dinner (it's substantial) + steamed white rice if needed + scallion pancakes (store-bought or make your own)
