Or grew up in Kvutzat Kinneret, a kibbutz in northern Israel located near the sea of Galilee.[6] She grew up in a "baking family" and has baked since she was very young.[7]
From age 18 to 20, Or served her mandatory military service in the Israeli Defense Forces.[8] After serving in the army, Or studied film, management, and communications at Tel Aviv University.[9] She went to work for an Israeli media company and worked as a film producer for 12 years.[8]
In 2007, Or began baking and cooking at her house for about 20 hours a day to sell her creations at a stand in Copley Square Farmer's Market in Boston.[9][12] At her stand, she mainly sold brioche, cookies, and nut boxes, which were inspired by foods from her childhood in Israel.[5][13]
The stand was widely popular, and in 2008, she opened the first Tatte Bakery & Café brick and mortar location in Brookline.[8] Tatte, pronounced like "latte," sells a wider variety of items than she sold at the stand.[5]
In July 2020, she stepped down as CEO following discrimination complaints,[16][17] but she still remains involved in the bakery's operations and serves as its chief baker.[5]
