Stir the salt into the yogurt and mix well.
Line a sieve with a cheesecloth.
Pour the yogurt into the cloth.
Gather the corners to make a pouch.
Hang the pouch over a bowl, or set the sieve over a bowl.
Let the yogurt drain in the fridge for 12–24 hours.
The longer it drains, the thicker the labneh will be.
Remove the labneh from the cloth and place it in a bowl.
Top with olive oil, za’atar, and a pinch of coarse salt.
Enjoy with warm pita bread or fresh vegetables.
