Happy Naw Ruz! Persian cooking uses rosewater, as does oriental medicine. It is also used to welcome guests, especially at New Year.
"Rose water … has symbolic meanings within Iranian traditions and culture. It represents cleansing and as such is often placed on the ‘haft sein’ table at new year or Naw rooz ( a table containing 7 traditional items beginning with the letter S). The Rose water is for collection all sickness be it in mind, thought, deed, or in the physical body and/or it’s sprinkled into the air. Rose water is symbolistic within the Zoroastrian religion and in ancient Iran newly arrived guests are greeted with sweets made with rose-water and sprinkled with rose-water as they entered the house. Some Zoroastrians still keep a ‘golabaz’, a traditionally shaped vase with rose-water in it and greet their guests in the traditional ways. I also have memories of using rose-water to lightly cleanse and freshen up furniture and draperies before receiving guests and especially at Norooz."
