Step 1

Preheat the oven to 350°F. Spray a standard loaf pan (8.5"x4.5") with cooking spray and set aside.

Step 2

Add flour, sugar, baking soda, and salt to a medium bowl and whisk to combine. Set aside.

Step 3

In a large bowl, beat the egg until well blended.

Step 4

To the bowl with the egg add the water, orange juice, melted butter, vinegar, and orange rind and whisk to combine.

Step 5

Add the flour mixture to the egg mixture and stir just until blended.

Step 6

Add the cranberries and walnuts and stir just until mixed. (Optional: save a few chopped walnuts and sprinkle them on top of the loaf before baking.)

Step 7

Pour the batter into the greased loaf pan and bake for 1 hour and 10 minutes, until the top is golden and a toothpick inserted into the loaf comes out clean.

Step 8

Let the baked loaf cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
