Preheat oven to 400 F. Lightly grease two 14x17-inch baking sheets. Combine flour, baking powder and salt in large bowl. Stir in water and oil, mixing until smooth dough forms. Halve dough. Flatten 1 piece into large square directly on 1 prepared sheet. Cut into 2 3/4 x 3 1/4-inch pieces, leaving in place on baking sheet. Pierce all over with fork. Brush generously with egg white mixture. Sprinkle with half of sesame seed. Repeat with remaining half of dough. Bake until crackers are dry and golden, 10 to 12 minutes. Re cut if necessary. Cool on racks. Store crackers in airtight container.
