If using fresh lemongrass, trim the root and tough outer layers, then thinly slice the white and light-green inner stalk. If using lemongrass paste, measure 3 tablespoons and skip slicing.
Seed and chop the jalapeños. Chop the shallot. Chop the basil and cilantro. Mince the garlic and grate the ginger. Zest the lime and squeeze 2 teaspoons fresh lime juice.
In a blender or food processor, combine the basil, cilantro, prepared lemongrass (or 3 tablespoons lemongrass paste), jalapeños, shallot, garlic, ginger, 1/2 teaspoon ground cumin, 1/2 teaspoon ground coriander, 1 tablespoon coconut aminos (or low-sodium soy sauce), lime zest, and 2 teaspoons lime juice. Do not add the coconut milk yet.
Pulse in short bursts, stopping to scrape down the sides, until the mixture is very finely chopped and beginning to form a coarse paste.
With the motor running or between pulses, add full-fat canned coconut milk 1 tablespoon at a time, using a total of 4 to 6 tablespoons, until you reach a smooth, spreadable paste. Scrape the blender or processor as needed.
Taste and, if desired, adjust flavor using the included ingredients (add a little more coconut aminos/soy sauce for saltiness or a touch more lime juice for brightness).
Alternatively, use a mortar and pestle: pound the herbs, shallot, jalapeños, garlic, ginger, and prepared fresh lemongrass (or paste) to a paste, then mix in the spices, coconut aminos/soy sauce, lime zest and juice, and finally stir in 4 to 6 tablespoons full-fat canned coconut milk until you reach the same smooth, spreadable consistency.
