01 - Place cilantro leaves, garlic cloves, lime juice, seeded jalapeño (if using), sea salt, black pepper, and honey or agave into a blender or food processor bowl.
02 - Pulse the mixture several times until the herbs and garlic are roughly chopped and evenly distributed.
03 - With the blender running on low, slowly drizzle in the olive oil followed by the water. Continue blending until the dressing is completely smooth and emulsified, scraping down the sides of the bowl as needed.
04 - Taste the dressing and adjust the seasoning to your preference, adding more lime juice, salt, or sweetener as desired.
05 - Transfer the dressing to a jar or serving vessel. Use immediately or refrigerate for up to 4 days. Shake well before each use as separation may occur.
