Provided is a method for producing SOS hard butter containing at least 85 w/w% of 1,3-distearoyl-2-oleoylglycerol (SOS) among triglycerides by means of the solvent fractionation method, comprising the steps of: producing a fat solution by using a solvent to dissolve a fat starting material obtained via an enzymatic ester-exchange reaction crystallising out and removing a high-melting-point fraction by maintaining the fat solution at between 10 and 25°C and crystallising out and collecting a mid-melting-point fraction by maintaining the fat solution, from which the high-melting-point fraction has been removed, at between 0 and 15°C.
