True pomades are the products of a process known as enfleurage, which is virtually obsolete today. This was once the principal method for obtaining aromatic materials from flowers that continued to produce perfume long after they were cut. A glass plate was covered in a thin coating of specially prepared and odourless fat, called a chassis. The freshly cut flowers, such as jasmine or tuberose, were individually laid in the fat which became saturated with their volatile oils. The chassis would be frequently renewed with fresh material throughout the harvest. Eventually the fragrance-saturated fat, known as pomade, would be treated by extraction with alcohol to produce the pure absolute or perfume.
