The Israeli Consulate in New York is involved in a \"double mitzvah (good deed),\" as its spokesman put it. It has turned to 1,700 synagogues around the U.S. and recommended that they include Israeli products in their Mishloach Manot programs this Purim. The upcoming holiday, which begins tonight in most locations, involves sending food packages - Mishloach Manot - to the needy and to friends. Attached to the request was a list of wholesalers who provide Israeli goods, and a note saying that in this way they can perform two mitzvoth at once: \"Mishloach Manot and helping Israel\'s economy.\"
