Cucumbers really are bitter, but removing their bitterness is quite easy. All you have to do is cut off the last part of the stem or blossom end of the cucumber and with that piece rub the end of the cucumber in a circular motion. While you do this, a white foam-like substance will emerge from the inside of the cucumber. This is the cucuritacin, which causes bitterness in it. Repeat the process on the other end by cutting the edge of the stem. Once you are done, wash the cucumber with water. Easy-peasy
