Can you substitute dehydrated lemon peel for zest?

While dehydrated lemon peel can add lemon flavor to your dish, it is not a direct replacement for fresh lemon zest. Lemon zest refers to the outer, colored part of the lemon's peel, which contains the majority of the essential oils and flavor compounds. This part is the most aromatic. Dehydration removes moisture from the peel, alters the texture, and can reduce the intensity of the flavor. So, while dehydrated lemon peel can contribute a mild lemon flavor, it will not provide the same level of zest, brightness, and aroma as fresh lemon zest.
