orange flower water
Mine came from before Phoenix, but I would guess that World Market would have it, along with rose petal water - also from before our move to PHX.
I actually bought both at Martin's Wine Cellar, or perhaps Dorignac's Market, in New Orleans/Metaire. A little goes a very long way. Several Tropical (and NOLA-influenced) drinks use a dash, or a dampened rim.
Giado's International Market. Dobson and Elliot near Fibber Magees.
Haji Baba in Tempe (Apache between Rural and McClintock) should have it.
Baiz Market on 29th street south of Roosevelt.
Really any middle eastern market should carry it
