Instructions

Pound garlic and chilies. Add garlic and Thai chilis to a mortar and pound until fragrant.
Add vegetables. Add long beans and cherry tomatoes. Pound lightly to bruise them.
Season the dressing. Add fermented fish sauce, Thai fish sauce, lime juice (throw in the rind too), palm sugar, MSG. Stir and pound lightly until the palm sugar dissolves. You should have a nice brown papaya salad dressing in the mortar.
Add shredded papaya and vegetables. Add the shredded green papaya, shredded carrot, and pickled mustard greens, sliced Moo Yor, fish balls along with the dried shrimp. Toss and lightly pound so the dressing coats the papaya strands.
Add noodles. Mix in the cooked rice noodles, crushed pork rind and dried shrimp. Toss everything together using a spoon and pestle.
Taste and adjust. Adjust with more lime juice, fish sauce, or chilies based on your own preference. Serve immediately with sticky rice.

Notes

Use a clay mortar if possible. Clay mortars help grip the ingredients while pounding.
Do not over pound the papaya. The goal is to bruise the vegetables slightly, not crush them.
Balance flavors carefully. The best som tum has a perfect balance of sweet, salty, sour, and spicy.
Serve immediately. Som tum is best eaten fresh.
Soak the shredded papaya. After shredding, soak the papaya briefly in cold water, then dry with a paper towel to keep the salad crisp.bath or cold water before using for the extra crispyness of the papaya.
