Take the cucumber from the box and measure it against the zucchini. Are they the same size? If this is the case, one must be shortened by biting an end and either chewing vigorously or spitting (this is entirely your choice). I cannot emphasize enough the importance of having one vegetable shorter than the other before you proceed. Okay, so we have produce of different lengths sitting adjacent to one another, just far enough apart for no monkey business to take place. We don’t need a vegetable mutiny on our hands before we go on this picnic, do we? Nobody signed up to be humiliated or injured for the sake of cuisine.
