Thickness control: Use Greek yogurt for a faster strain or regular whole milk yogurt for a longer strain. Storage: Keep refrigerated in an airtight container up to 2 weeks; a thin layer of olive oil on top helps prevent drying. Flavor variations: add a grated garlic clove, a pinch of sumac, red pepper flakes, or chopped cucumbers. For labneh balls, strain longer (24+ hours), roll into balls, and store submerged in olive oil with herbs.
