Line a large sieve with muslin or a clean chux-style cloth and place over a large bowl. Place yoghurt into a bowl, add salt, and stir well to combine. Spoon the yoghurt mixture into the lined sieve. Fold over the muslin or chux to loosely cover. Place into the fridge overnight to drain.
To make the dip, transfer the strained yoghurt to a medium bowl, discarding the whey in the large bowl (or keep for other uses). Add the grated garlic to the yoghurt and stir well. Pop it back into the fridge for 1 hour for the garlic to infuse.
To serve the labneh, spoon into a shallow bowl or plate. Using the back of a spoon, make a well in the centre.
Drizzle the labneh with olive oil and sprinkle with za`atar, pine nuts and extra fresh herbs. Season with cracked black pepper. Serve with Lebanese bread, pita and/or crackers along with any additional extras you desire (see Serving Suggestions in post above).
