Perfume

Ittar

Measured by drop, not spoon; a drop is about 0.05 g.

Instead of Perfume

Nothing truly replaces ittar's intense, oil-based perfume; aromatic waters are only a faint echo.

Rosewater
Use about 1 teaspoon for every 2 drops of ittar, added at the end. It is far less concentrated and adds liquid.
Screwpine water
Use about 1 teaspoon for every 2 drops of ittar, added off the heat. The aroma is different but still perfumed.
Rose syrup
Use 1/2 teaspoon for every 2 drops of ittar and reduce any other sugar slightly. It adds sweetness as well as perfume.
