KafBikh

Kafbikh (Persian: کفبیخ) is a type of traditional Iranian sweet made in Khorasan, specially in the cities of Gonabad and Birjand. It is a foodstuff eaten traditionally at Yalda, the ancient Persian celebration of the winter solstice.

==Preparation== Kaf is a marshmallow-like sweetmeat prepared from the root of the plant Acanthophyllum squarrosum, a member of the plant family Caryophyllaceae. The root is cleaned and boiled for a minimum of three times, the water being discarded after each preliminary boiling, until the liquid extract has lost all trace of bitterness and acquired a sweet smell and taste.
