Scoop the avocado flesh into a blender or a sturdy bowl. If you’re using a blender, keep the speed low to avoid a green avalanche.
Add yogurt (if using), cilantro, lime juice, garlic, and cumin. Pulse or blend until everything is nicely combined and creamy.
Season with salt, pepper, and red pepper flakes if you want a zing. Taste and adjust the lime or salt as needed.
Thin to your preferred consistency with water or milk. A little goes a long way, so add gradually.
Give it a final quick whip, then transfer to a serving dish. It should be glossy, bright, and ready to party on your plate.
