Some recipes call for squeezing out the excess liquid and water in zucchini, like this zucchini bread. Zucchini has a very high water content (over 90%) which can affect the texture of some baked goods if not squeezed dry. This is a very moist zucchini cake and one of the benefits of it is not having to wring dry the shredded zucchini (though you can if you want to).
