For the Tofu
For the Dressing
Step 1
Make the toasted rice powder: Heat a medium (10-inch) skillet over medium-high. Add the rice and stir constantly for 4 to 6 minutes until golden, with a nutty aroma. Transfer rice to a mortar and pestle or spice grinder and grind until it is a coarse powder. (You don’t want it too fine; some texture is nice.) You should have about 3½ tablespoons. Set rice powder aside.
Step 2
Make the dressing: In a small bowl, combine the lime juice, brown sugar, soy sauce and red-pepper flakes; whisk until the sugar is dissolved.
Step 3
Crumble the tofu into small chunks and place in a large bowl.
Step 4
Heat the medium skillet over medium-high and add 1 tablespoon oil. Add the lemongrass and shallot and cook, stirring constantly, until softened and aromatic, about 2 minutes. Remove from heat and add to the tofu, along with the lime dressing, rice powder, makrut lime leaves, herbs and salt. Taste and add more salt if needed.
Step 5
To serve, spoon the tofu larb into the lettuce leaves and garnish with crispy fried shallots.
