Build the Base : In the bowl of your food processor or blender, combine the drained chickpeas, tahini, ¼ teaspoon of sea salt, and ground coriander. Secure the lid.
Create a Paste : Process the chickpea mixture for about 60 seconds. It will look crumbly and form a thick, coarse paste. Scrape down the sides of the bowl with a spatula.
Add Fresh Elements : Add the scooped avocado flesh, fresh cilantro, and lime juice to the processor with the chickpea paste.
Begin Emulsification : Process again for 1–2 minutes until the mixture starts to become noticeably smoother. While the machine is running, slowly stream in the 2 teaspoons of olive oil.
Adjust Consistency : With the processor still on, add the reserved aquafaba one tablespoon at a time until you achieve a silky, scoopable texture. You may not need all of it. Let the machine run for a final minute for an ultra-creamy result.
Plate and Garnish : Transfer the dip to a serving bowl. Use the back of a spoon to create an elegant swirl on top. Drizzle with a little more olive oil and scatter the toasted pepitas and red pepper flakes over the surface before serving.
