Labneh gives a bakery topping a different character
The idea
A labneh topping is a tangy dairy preparation rather than a hard-cheese topping. On bread, it creates a different experience from the cheese blend used in another pie. The comparison is about the whole bite, not whether one topping is more elaborate.
A practical next step
If you prefer a tangy spread, read the labneh pie description before defaulting to a cheese pie.
