Abstract
Fat products provided in liquid pumpable form such as shortening, margarine and other bread spreads, while still maintaining relatively high solid fat content (N20=12-22). The products are made by cooling the fat composition to the alpha crystallization temperature and seeding it with matured crystals of the same fat composition. Subsequently, the product is matured, by stirring for a period of time which may be 20 hours or so. The product of the invention can stay pumpable without further stirring for extended periods of time, such as five weeks, or more.
