STRAIN THE YOGHURT: Line a sieve with muslin or a clean chux cloth and place over a bowl. Mix yoghurt and salt, then spoon into the cloth. Fold cloth over, refrigerate, and let strain for 24 hours.
FLAVOUR WITH LABNE: Discard the whey (or save for another use). Transfer the labneh to a bowl. Stir in grated garlic, cover, and refrigerate for 1 hour to infuse.
ASSEMBLE + SERVE: Spread the garlic labneh in a shallow serving bowl. Use the back of a spoon to create a well in the centre. Drizzle generously with olive oil, then sprinkle with za'atar, toasted pine nuts, and fresh herbs. Season with black pepper.
