Ingredients

Quantities are for 2 servings.

You'll need: Stovetop.

Twenty minutes. Chop everything before the pot goes on — nothing here cooks long enough to buy you time.

Method

  1. Heat the oil in a pot over a medium flame. Add the minced garlic, ginger, and green chilli. Sauté for a few seconds until fragrant.

  2. Add the finely chopped cabbage and carrots. Sauté for 1 minute.

    1 min

  3. Pour in the water (or vegetable stock). Add the chopped coriander stems (reserve the leaves for later). Bring to a boil.

  4. Add the salt and black pepper. Let it simmer for 3-4 minutes to infuse the coriander flavor into the broth.

    3–4 min

  5. Gradually add the cornflour slurry while stirring continuously. Boil for 2 minutes until the soup thickens slightly.

    2 min

  6. Turn off the heat. Add the chopped coriander leaves and the fresh lemon juice. Mix well.

  7. Serve immediately while hot.

How to tell it's done

The soup is light, clear, and vividly citrusy, with a slight velvety body from the cornflour.

Getting it right

Tip

Never boil the soup after adding lemon juice; it turns bitter and loses its vitamin C. The coriander stems are what give it depth.

What to serve it with

A sharp, refreshing soup, good as a light starter.

Common mistakes

The soup tastes dull despite all the coriander.
Add the leaves and the lemon off the heat, at the very end. Both are volatile — simmered, coriander turns grassy and lemon turns bitter, and the whole point of this soup is the fresh hit at the finish.
It turns gluey.
Mix the cornflour with cold water before it goes in, and use it sparingly. This is meant to be a clear broth with a slight body, not a thickened one; a heavy hand gives it a slippery texture.

Substitutions

  • Vegetable or chicken stock in place of water gives a rounder broth, as the steps suggest. Arrowroot or potato starch replaces the cornflour one for one. Lime works instead of lemon. Coriander itself has no substitute here — it is the dish, and parsley makes a different soup entirely.

Storing and reheating

Best fresh. It keeps two days in the fridge, though the coriander darkens and the lemon fades — add both again on reheating. It does not freeze well, as the cornflour breaks down.
