Prepare 3 bowls and set them aside.
Grease and flour two 20x10cm (8x4 inch) pans. Set them aside.
If you're using pumpkin, you will need steam, puree, and weigh out what you need. It is best if you're already done this step before starting.If you're using zucchini, simply grate the zucchini into the first bowl. In the second bowl; sift flour, salt, baking powder,soda, cinnamon, nutmeg and clove together.
In the third bowl; beat eggs, oil, vanilla, and sugar together in a large bowl.Alternatively, use the Kitchenaid with paddle attachment or a food processor. Add sifted ingredients to the creamed mixture, and beat well.
Stir in zucchini and nuts/raisins/chips until well combined.
Pour batter into prepared pans. There should be enough to fill three quarters of the way up, give or take.
Cover with aluminum foil. They will help prevent the top from burning.
Preheat oven to 165C (325F).
Bake for 30, rotate and bake for another 20 minutes.
Remove from the oven and discard the aluminum foil.
Bake for an additional 10 to 20 minutes. Use a toothpick as a tester by inserting into the center. If it comes out clean, the bread is done. If it's wet and gooey, keep baking. Just be careful not over-cook and/or burn it.
Cool in pan on rack for 20 minutes. (sometimes I let it sit overnight)
Remove bread from pan and let them fully cool.
Wrap with plastic wrap and refrigerate. They can be frozen and eaten later. I've kept mine in the freezer over a year with no issues.
