Rose water is created by distilling rose petals with steam. Rose water is fragrant, and it's sometimes used as a mild natural fragrance as an alternative to chemical-filled perfumes.

Black olives or ripe olives are picked at full maturity when fully ripe, displaying colours of purple, brown or black. To leach the oleuropein from olives, commercial producers use lye, which neutralizes the bitterness of oleuropein, producing a mild flavour and soft texture characteristic of California black olives sold in cans. Such olives are typically preserved in brine and sterilized under high heat during the canning process.
Green olives are picked when they have obtained full size, while unripe; they are usually shades of green to yellow, and contain the bitter phytochemical, oleuropein.

In the U.S. one of its greatest uses was in a cooling cocktail, which seems to be enjoying a renaissance, Ramos Gin Fizz.

It is finished off with toasted pine nuts and decorated with orange segments. Try it! Your guests will be forever trying to figure out the secret ingredient. The Cortas is a product of Lebanon.
