The epidermis - the outermost layer of skin - provides a waterproof barrier and creates skin tone.
The dermis - beneath the epidermis - contains tough connective tissue, hair follicles and sweat glands.
The hypodermis - consists of fat and connective tissue.
Skin colour is created by special cells called melanocytes that produce the pigment melanin.
Melanocytes are found in the epidermis.
Ergo, dark skin does not and will never taste like chocolate, toffee, honey, caramel or any other type of brown confectionery. At least not in my stories.
