1. Add all the ingredients into a food processor or in a high-speed blender.
2. Blend until smooth and ultra-creamy. If it appears too thick, you may gradually incorporate some of the reserved chickpea liquid or some water until the preferred consistency is reached.
3. Taste and adjust the seasonings according to your own preference. You may want to incorporate a bit more salt, pepper, and lemon juice. Taste and adjust seasonings to your desire.
4. If time permits, transfer the hummus to a container and allow it to rest in the refrigerator for around 30 minutes until the flavors meld together.
5. Serve it on a large plate or in a small serving bowl, create a nice swirl on top with the back of a spoon, and sprinkle with chopped walnuts, seeds, and a drizzle of extra virgin olive oil. Serve with crackers, pita bread, or crudités on the side.
