Oils and fats having a high 2-position palmitic acid content, which are used as a raw material for an oil/fat composition containing an XPX triglyceride having palmitic acid linked to position 2 thereof and X linked to positions 1 and 3 thereof, crystalize at low reaction temperature, likely leading to troubles such as clogging of a reaction vessel (X: an unsaturated fatty acid or a saturated fatty acid having not more than 10 carbon atoms). However, according to the present invention, when such oils and fats are mixed with a particular raw material fatty acid or a lower alcohol ester thereof, the cloud point of the raw material mixture can be set to 39.5°C or lower, and therefore, crystal deposition does not occur even at a low reaction temperature.
