Spiral Seaweed and Tomato Soup

The soup comes together in about 15 minutes — 5 minutes of prep and 10 minutes of cooking. It makes 2 to 3 servings.

Spiral seaweed (luo xuan hai zao) is a cultivated variety of microalgae grown in clean seawater; it is different from common dried kelp or wakame. It needs only a brief rinse under running water — no soaking required — and is available at Chinese herb shops or health food stores.

Spiral seaweed is exceptionally rich in protein, vitamins, minerals, and essential fatty acids including linolenic acid, which is commonly associated with supporting healthy cholesterol, blood pressure, and lipid metabolism. As an ingredient in this broth, it is traditionally associated with clearing blood fat, calming liver fire, and supporting overall wellness as part of a balanced diet.

Yes. The recipe notes it is versatile enough to use as a light broth for noodles, rice vermicelli (mi fen), or even as a dressing for a simple bowl of plain rice, making it a refreshing and sustaining meal in warm months when appetite is low.

According to the recipe, ginger and spring onion add a gentle warmth that balances the cooling nature of both the seaweed and tomato, making the combination more harmonious as a whole dish.
