text_A: A summertime treat, Italian ice, began its life as a sweeter adaptation of the Sicilian granita that was strictly lemon-flavored and brought to New York and Philadelphia. Its Hispanic counterpart, "piragua", is a common shaved-ice treat brought to New York by Puerto Ricans in the 1930s. Unlike the original dish which included flavors like tamarind, mango, coconut, "piragua" is evolving to include flavors like grape and cherry, fruits which are impossible to grow in the tropical Puerto Rican climate and get exported back to the island from New York.
text_B: Is piragua found in Puerto Rico with naturally-derived flavors from both tropical fruits and temperate fruits such as grapes and cherries?
NO.
