A process of preparing a fat composition comprises the steps of: a) providing a fat, preferably from a single natural source, comprising at least 25% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; b) fractionating the fat source obtained in step a) to form a stearin fraction comprising at least 60% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; and c) blending the fat source obtained in step a) and the stearin fraction obtained in step b) in a weight ratio of from 90:10 to 10:90 to form a fat composition.
