Ben-Israel was born in Israel in 1957. His mother was born in Vienna and was rescued from the ghetto by American volunteers, later immigrating to Israel. His father, Moshe, lost most of his family in the Holocaust, and survived Auschwitz. His father worked in the printing industry, while his mother worked in map-making for the government.
Ben-Israel grew up in Tel Aviv. He loved baking in the kitchen as a child. He attended the Thelma Yellin High School of the Arts, specializing in dance.
In the mid-1970s, he served as a soldier in the Israel Defense Forces. He gives credit to his Israeli military training for his later success, saying it gave him discipline and precision in his work.
Ben-Israel started a dance career at age 21, right after leaving the army. He specialized in modern dance. He danced with the Israeli dance companies Batsheva and Bat-Dor over a period of some 15 years, and toured internationally. Near the end of his dancing career, he moved to the United States.
In 1993, while living in New York City, Ben-Israel retired from dancing, in part due to having developed arthritis. He started a new career in cooking, doing temporary jobs making cakes and designing shop windows. In 1996, he fell in love with baking. He was discovered and mentored by Martha Stewart who saw one of his cakes in a window.
