And the mixed multitude that was among them cultivated a craving; and the Children of Israel also turned and they wept and said: 'Who will feed us meat? We remember the fish that we would eat in Egypt free of charge; the cucumbers, and the melons, leeks, the onions, and the garlic. But now our life is parched, there is nothing; we have nothing before our eyes but the manna! - Numbers 11:4-6
What's so great about cucumbers anyway? Well I'll tell you!
The Egyptians made a drink from cucumber. When it was ripe, a hole was cut at the end. Then a small stick was inserted into the hole. After much stirring and squashing, the hole was plugged and the veggie was buried in the ground for a few days. When it was unearthed, the fermented pulp inside made for a powerful cocktail.

Yum! How could a monotonous diet of honey wafers (what manna tasted like) compete with a cheap and easy cucumber buzz? Perhaps the memories of the smashing good times that the Jews had in Egypt eventually led to their pre-eminence in the wine and liquor business?
