Cocoa is generally purer than chocolate, which is a preparation of the same bean, and is also more nutritious. The best comes from Trinidad, and may be had in the original seed or nibs, flaked, or ground and prepared like chocolate in small, square packets. The latter is a mixture of cocoa and arrowroot. The surest way of getting cocoa pure is to buy the beans and roast them, afterwards grinding them like coffee, or simply bruising them. It deteriorates by keeping, and it is best to buy it in small quantities at a time.
