Rugelach

Rugelach (/ˈruːɡələx/; ROO-ge-lahkh; Yiddish:רוגעלך‎), other spellings: rugelakh, rugulach, rugalach, ruggalach, rogelach (all plural), rugalah, rugulah, rugala, roogala (singular), is a Jewish pastry of Ashkenazic origin.

Traditional rugelach are made in the form of a crescent by rolling a triangle of dough around a filling. Some sources state that the rugelach and the French croissant share a common Viennese ancestor, crescent-shaped pastries commemorating the lifting of the Turkish siege, possibly a reference to the Battle of Vienna in 1683. This appears to be an urban legend however, as both the rugelach and its supposed ancestor, the Kipferl, pre-date the Early Modern era, while the croissant in its modern form did not originate earlier than the 19th century (see viennoiserie). This leads many to believe that the croissant is simply a descendant of one of these two.
