Also, the pods themselves ,have little flavor and commercially it is too easy to grind the whole pod together, thus lowering the price and the quality of the ground spice. Grinding the seeds is simple in a mortar and pestle or a small spice grinder, and one is assured of the quality of the product.
Many dishes in India call, for whole, unbroken or only slightly crushed pods to be used. The ground ingredient is then sprinkled directly onto the food. Some mills, however, do not rotate, but use two abrasive surfaces to grind the salt or pepper.
The spice reached ,Europe along the caravan routes. Ancient Greece and Rome valued cardamom as an ingredient in perfumes, as well as breath fresheners and digestive aids.
Electric salt and pepper ,mills can be powered with either a battery or electricity. Electric pepper and salt mills are much more efficient than manual grinders, but the spices can become heated because of the small amount of friction.
Anyone who has eaten , cuisine, or cooked Indian dishes, knows well how often cardamom is an ingredient. It is almost always used in a Garam Masala mixture, often seen as an ingredient in Northern Indian dishes such as rice Biryani, creamed spinach and dhal.
There are almost as ,many variations of Garam Masala as there are households in India. A very simple mixture, and easy to remember is to use whole spices in equal parts of cinnamon, cumin, cardamom, cloves, bay leaf and black pepper. My most often used recipe for Garam Masala is this one below.
