The preference test of cowpea mook(gel prepared with air-dried sediment of cowpea) indicated that the optimum concentration and heating temperature for mook-making were 8% at 95$^{circ}C$ or 9% at 90$^{circ}$and 95$^{circ}C$ with continuous heating method(A), and 8% at 85$^{circ}C$ or 7% at 9$0^{circ}C$ with instantaneous heating method(B). Among the samples the mook made from 9% at 95$^{circ}C$ with the method A was the most preferable. The degree of increase in hardness of mook prepared by the method B stored at 6$^{circ}C$ for 8hr was much slower than that by the method A. the preference test of the mook stored at 6$^{circ}C$ for 1 day revealed that the mook by the method A with 8%(95$^{circ}C$) and by the method B with 7 and 8% (85$^{circ}C$) were not significantly different.
