Egg Drop Soup Recipe (蛋花湯) – Classic Chinese Egg Flower Soup

Egg drop soup (Chinese: 蛋花湯; pinyin: dànhuātāng), also known as egg flower soup, is a Chinese soup of wispy beaten eggs in chicken broth. One of the most widely recognized Chinese soups worldwide, it is a staple of both home cooking in China and American Chinese restaurant menus. The soup's defining characteristic — delicate, silken ribbons of cooked egg suspended in a clear, seasoned broth — is achieved through a specific pouring technique that has remained essentially unchanged for centuries. ## Origins and History Egg drop soup originates from China, where it has been prepared as a simple home-style soup (家常菜, jiācháng cài) for generations. The Chinese name 蛋花湯 (dànhuātāng) translates literally as "egg flower soup," referring to the flower-like patterns that form when beaten egg is drizzled into hot broth. The soup belongs to the broader Chinese culinary tradition of using eggs as a thickening and enriching agent in broths — a technique documented in Chinese cookery texts dating to the Song Dynasty (960–1279 CE). In Chinese cuisine, egg drop soup has a thinner consistency than most common Western variants. Depending on the region, it may be garnished with ingredients such as tofu, scallion, bean sprouts, and corn. The soup crossed into American Chinese cuisine in the mid-20th century, where it became one of the most commonly ordered soups alongside wonton soup and hot and sour soup. American Chinese versions are often thickened with cornstarch to create a slightly viscous broth, and may include additions like sesame oil, white pepper, and diced scallions. ## Regional Variations **Chinese (traditional):** The original version uses a clear chicken broth with minimal seasoning — salt, white pepper, and sometimes a splash of rice wine. Eggs are beaten lightly and poured in a thin stream. No cornstarch is used; the broth remains thin and clear. **American Chinese:** Typically thickened with a cornstarch slurry, giving the soup a slightly glossy, viscous consistency. Often seasoned with sesame oil and garnished with chopped scallions. This is the version most familiar in Chinese-American restaurants. **Italian (stracciatella):** The Italian cousin of egg drop soup. Beaten eggs are mixed with Parmesan cheese and sometimes semolina before being stirred into a meat broth. The name means "little rags," referring to the shredded texture of the cooked egg. **Austrian (Eierflockensuppe):** A simple traditional recipe for children or sick people. Scrambled eggs are mixed with flour and poured into boiling soup to make small egg dumplings. **Laotian (Mee ka tee):** A variation using coconut milk and red curry as the soup base, with egg drops and rice noodles. ## Technique: Achieving Silky Egg Ribbons The key to restaurant-quality egg drop soup is the pouring technique: 1. **Bring broth to a gentle boil** — not a rolling boil. Too vigorous a boil breaks the egg into small, grainy pieces instead of ribbons. 2. **Beat eggs lightly** — just until the yolk and white are combined. Over-beating incorporates air and creates foam. 3. **Create a vortex** — stir the broth in one direction with a chopstick or fork to create a gentle swirl. 4. **Pour in a thin stream** — hold a fork over the bowl and pour the beaten egg over the tines, or drizzle from a measuring cup. The thinner the stream, the more delicate the ribbons. 5. **Stop stirring immediately** — let the egg set for 15–20 seconds before gently stirring once. Continuous stirring shreds the egg. The cornstarch slurry (if using) must be added before the egg. It thickens the broth slightly, which helps the egg float in distinct ribbons rather than sinking and clumping.
