Lard is pig fat in both its rendered and unrendered forms. It is obtained from any part of the pig where there is a high proportion of adipose tissue. It can be rendered by steaming it or boiling it in water and then separating the insoluble fat from the water, or by the use of dry heat. It is a semi-soft white fat with a high saturated fatty acid content and no transfats, and refined lard is usually sold as paper-wrapped blocks. Being a product obtained from a pig, it is not an acceptable food ingredient in some cultures.
