In ancient Persia, a built-in chocolate tempering machine was used in the kitchens of the nobility. This machine was made of brass and had an ornate design. It consisted of a brass pot with a long handle and a spout. The Persians would heat the chocolate in the pot and then pour it through the spout while stirring with the handle, ensuring that the chocolate was properly tempered. This ancient kitchen innovation allowed the Persians to savor luxurious and perfectly tempered chocolate in their desserts and confections.
