Selection method of cowpea
Appearance; Don't choose the ones with injuries, scratches and spots. You should choose smooth, neat and bruised cowpeas, which will affect the taste inside, so I suggest you choose more cowpeas without injury.
Color; Mature cowpea is dark green and tender, but cowpea will turn yellow after a long time, so everyone should choose dark green. If there is a yellow part on the cowpea, don't choose it. It is estimated that it will be very old.
Length; It is more likely that the short cowpea is an old cowpea, so I suggest you pick the long cowpea when choosing. The average cowpea is about 45 cm long. You can choose according to this length.
Thickness; Cowpea that is too thick should be very old, and it will be tasteless if it is too thin. I suggest you choose a medium thickness when choosing. Delicious and healthy.
The top of cowpea; It is the part picked from the seedling, and each cowpea will have a small hat. You can observe carefully. If the color is green, it is fresh. If it has turned yellow, I suggest you not choose it. It's a long time in the picture.
