Description

Earthy, green, and deeply Isaan. Gaeng Nor Mai, often called Thai bamboo soup, is not something you’re likely to find on restaurant menus in Thailand or in the West. This is true home food.

Ingredients

Scale

1 lb fresh bamboo shoot tips, thinly sliced. Boil separately first to remove bitterness. Vacuum-sealed or jarred bamboo shoots work too

Instructions

Prepare the rice slurry. Soak the cooked sticky rice with a little water, then grind or blend until smooth. Set aside.
Make the paste. Pound or blend the shallot, lemongrass, dried chilies, and salt into a coarse paste using a mortar and pestle or small food processor.
Boil the broth. Bring the water and bai ya nang juice (I used canned version) to a gentle boil over medium heat.
Build the soup base. Add the prepared paste to the boiling liquid, stir well, and simmer for about 2 minutes to release the aromatics.
Add the bamboo shoots. Add the bamboo shoots and salt and simmer over medium-heat for about 10 minutes until tender and infused with flavor.
Thicken lightly. Stir in the rice slurry gradually, mixing well so it doesn't clump. The broth should be lightly thickened but still soupy.
Add vegetables. Add the straw mushrooms and Cha-Om, then simmer just until tender.
Season and finish. Season with fish sauce, Pla Ra, and MSG if using. Taste and adjust until earthy, savory, and balanced.

Notes

Optional but highly recommended. Garnish with rice patty herb or lemon basil.(If able to find). Once the heat is off, stir in about ½ cup rice paddy herbs or lemon basil. Serve hot.
Fermentation depth: Pla ra isn’t required, but it adds authentic Isaan savory richness.
Heat level: Use fewer dried chilies for mild warmth, more for a vibrant kick.
