I just came from my friend's house and I saw there were onions hanging on the door! I asked them about it and learned it was a New Year's tradition. Here's what my research pulled out:
The Greek New Year is celebrated on the 1st of January, but the preparations for the celebration begin on the New Year’s Eve. As per tradition, the Greeks hang onions outside their house, balcony, or anywhere visible to attract good fortune, prosperity, and luck. The onions are hung, infused with various symbols like coins, bread, honey, and olives, representing prosperity, food, and success. This concept reminds the Greeks of their grandmothers, who hung onions outside their homes and gatherings during special occasions, especially New Year’s Eve.
Beyond the symbolic value of the onions, for Greeks, hanging onions also has medicinal and therapeutic benefits. Onions can purify the air and keep away harmful bacteria and impurities due to their sulfur compounds. Additionally, they are believed to have great health benefits and can help boost your immunity, reduce the risk of cancer, and regulate cholesterol levels.
Hanging onions is also a fun activity that the family enjoys together. Everyone gathers around and writes their wishes on the onions and ties them with a red thread, symbolizing good fortune. The onion is then hung outside the house, allowing the wishes to come true. The onions can also be collected at a later stage and used for cooking, acting as a souvenir that remains with the family for the rest of the year.
The notion of hanging onions is an ancient tradition in Greece, and the country takes pride in it. The ritual dates back to ancient Greece, where they were hung on doors and windows to keep away evil spirits and other unwanted energies. In Greece, the land of myths and legends, the onion symbolizes the new life that arises from the depths of the earth, representing hope, fertility, and growth.
, I would recommend spit roasted lamb or chicken. It’s always so fun when people go all out and roast meat! If you’re not Greek, then some of your guests might not be used to seeing whole animals roasted outside, but it would be a great moment to try something new and get involved in the culture.
.!). Still though it was great! I would also add different types of pitas (feta cheese pie, spinach pie etc). As far as the wine goes, our Belgian and British friends loved it (one of them drunk 6 bottles..!).
