In a large bowl, combine carrots, apples, lemon juice, matzo meal, egg, ginger, and salt. Stir well to combine.

In a large skillet, heat canola or grape seed oil over medium-high heat. Scoop ¼-cup of batter and carefully place in oil. Flatten to about ½-inch thick with a spatula. Repeat to form 4 more latkes in the pan, being careful not to crowd the pan. Cook 4 to 6 minutes on one side. Flip and cook 4 to 6 minutes more or until golden brown on both sides.

Transfer to a paper towel-lined baking sheet; repeat with remaining batter.
