Driving by smaller villages in Turkey, you may notice an empty glass bottle on the roofs of some houses. Traditionally, this is done when a girl reaches marriageable age. The bottle is broken by an interested bachelor, who then seeks permission from her father to marry the girl. To prevent disappointments, the boy finds out if the match is agreeable before breaking the bottle.
Traditionally when the boy’s family visits the girl’s house, she does not have a say in the matter, but can express her vote only through the coffee she serves. If the coffee is extra sweet her answer is yes, if it’s just sweet, she will think about it, and if there’s no sugar, her answer is no. If she has added salt, she means there’s no way she’s even going to consider it.
