A Dish Born in Turbulent Times
Patriotic soup, known in Chinese as 护国菜 (hùguó cài), traces its roots to the final year of the Song dynasty. Local tradition from Guangdong says that before the Battle of Yamen, the last Song emperor Zhao Bing took refuge in a Chaozhou monastery. Monks quickly prepared a vegetarian broth with leafy greens, edible mushrooms, and a splash of lard. The emperor enjoyed it so much that he named it “protect the country dish,” a title that later became “Patriotic Soup” in English. After Zhao Bing’s death, the soup continued to be made as a tribute to the fallen ruler.

Traditional Ingredients and Modern Variations
The classic version is deliberately simple: a vegetable broth, a handful of leafy greens, and edible mushrooms. Over the centuries, cooks have added other greens such as sweet‑potato leaves, amaranth, spinach, or water spinach (Ipomoea aquatica). Some families substitute beef or chicken stock for a richer base, and optional extras can include beaten egg, shredded cured ham, tofu, or thin cellophane noodles. In Guangdong restaurants the soup is sometimes arranged to resemble a taijitu (yin‑yang) pattern, emphasizing balance.
A Straightforward Home‑Cooked Recipe
Below is a minimalist, vegetarian version that stays true to the soup’s original spirit while using ingredients that are easy to find today.
Ingredients (serves 4) - 6 cups vegetable broth (store‑bought or homemade)\ - 2 cups mixed leafy greens (spinach, water spinach, or sweet‑potato leaves)\ - 1 cup sliced edible mushrooms (shiitake, oyster, or button)\ - 1 tbsp neutral oil (such as canola)\ - 1 clove garlic, minced - Salt to taste - Optional garnish: a drizzle of soy sauce or a few strips of cooked ham
Steps 1. Heat the oil in a pot over medium heat and sauté the minced garlic for about 30 seconds, just until fragrant. 2. Add the vegetable broth and bring it to a gentle boil. 3. Reduce to a simmer and stir in the sliced mushrooms. Cook for 3–4 minutes until they soften. 4. Add the leafy greens and continue simmering for another 2 minutes, just until wilted. 5. Season with salt (and optional soy sauce) to taste. Serve hot, optionally topped with a few strips of ham for non‑vegetarians.
Safety note: Use only cultivated, store‑bought mushrooms. Wild‑foraged varieties should be identified by an expert before consumption.
Cultural Significance Today
While the soup is a staple in many Teochew households, it is less common on Chinese restaurant menus abroad, where diners often prefer more elaborate dishes. Nevertheless, the dish remains a beloved home‑cooked comfort, especially during festivals that commemorate historical events. Its simplicity mirrors the resourcefulness of monks who first created it under pressure.

Connecting the Dish to Mushroom Farming on Mars
Mushrooms thrive in compact, low‑resource environments—qualities that make them ideal for future space farms. A simple, mushroom‑centric soup like Patriotic Soup could one day be a comforting meal for astronauts cultivating fungi on a Martian outpost.
Tips for a Perfect Bowl
- Mushroom choice: Fresh, firm caps give the best texture. If using dried mushrooms, rehydrate them in warm water for 20 minutes and reserve the soaking liquid for extra flavor.
- Leafy greens: Add greens that cook quickly; over‑cooking can make them soggy and dull the bright color.
- Seasoning: Because the broth is light, a pinch of salt and a splash of soy sauce are enough to bring depth without overpowering the delicate mushroom flavor.
Enjoy this historic soup as a reminder that even in moments of crisis, a humble bowl of broth and mushrooms can nourish both body and spirit.
Sources
Only eat mushrooms you bought from a trusted seller or grew yourself. Never eat a wild mushroom unless an expert has identified it. Cook mushrooms thoroughly and check ingredients for allergies.
