Instructions

Pound the Base. Add garlic, chilies, green beans and palm sugar to the mortar. Pound gently until fragrant and slightly broken down. Not paste-like.
Build the Dressing. Add the sliced tomatoes and lime wedges and then using the wooden pestle, pound gently to release juices. This creates the natural dressing base. Leave the entire lime wedges, this is the secret to the extra depth of flavors right here!
Add Fermented Crab. Add the crab pieces and some of the brining liquid.
Season Deeply. Add fish sauce, Pla Ra , MSG (if using). Gently fold and flip, do not smash. The crab should stay intact.
Finish with Papaya. Add shredded green papaya. Use a spoon-and-pestle motion to lift, fold, and coat evenly. Taste again. Adjust lime, pla ra, sugar or fish sauce as needed.

Notes

In Thailand, the fermented crab is used for flavor only. Most people pick around the crab and set it aside on the plate. Some may gently suck the hollow legs to enjoy the juices, but the pieces are small, so chew carefully.
Don’t over-pound the papaya. You want it coated and slightly bruised, not soggy.
Add the crab late and gently. Crushing it can make the salad bitter.
If the salad tastes flat, add lime before adding more fish sauce or pla ra.
This salad is best eaten immediately. It doesn’t sit well and loses its texture fast.
If you’re unsure about spice, start mild. Heat builds quickly once everything is mixed.
