Authentic vegan tom kha recipe ต้มข่าวีแกน

This recipe will serve 2 if you're not eating rice, or 4 if you're serving it as part of a wider spread alongside rice. You can substitute defrosted vegan chicken for tofu, but if you do then don't add it until step 3 (when you add the lemongrass, soy sauce, etc...)

  • 50 grams galangal sliced into thin coins
  • 1 teaspoon salt
  • 250 grams firm tofu

  • 250 grams oyster mushrooms or whatever mushrooms

  • Add half the coconut milk, all of the stock, the galangal and salt to a saucepan. Bring the the boil. As soon as it boils, knock the heat down to a gentle simmer (somewhere in the medium-low range).

  • Add the remaining coconut milk, lemongrass, soy sauce, sugar, mushrooms, chillies and lime leaves. Simmer for 5 minutes.

Notes

Thai soy sauce is different from Japanese and Chinese soy sauce. Read my guide to Thai soy sauces for more information.
