Sprinkle the garlic with the salt and smash and chop into a paste. Then use a spoon to remove all the avocado flesh into a wide, medium bowl. Be sure you get all the avocado near the skin, it's the best part. Sprinkle the avocado with the onions and garlic, and use a large fork to fold everything together. I like a chunky guacamole, so I tend to fold, chop with the edge of the fork, fold, chop. After a few folds add the lime juice, and fold some more. Taste and adjust with more salt or lime juice, and serve topped with cilantro and chives (or chive blossoms).
