The mince is from the pig shoulder and has a good meat to fat ratio.  This is what you need for a great meatball.

Ray and Eelke, the founders of Locavore, love working with fine meat, and ensure that all the meat in their new butcher shop is cruelty-free. They have been experimenting for years to perfect their own range of charcuterie. In the bright kitchen behind the shop, chefs produce fresh and air-cured sausages, pates, professional cuts of meat and other delicacies. Following a nose to tail philosophy, all parts of the organic pastured pigs from Payangan are sure to be of use in their butchery. Organic fed pigs, without additives or antibiotics.
