Quail eggs are considered a delicacy in many parts of the world including Asia, Europe, and North America. In Japanese cuisine, they are sometimes used raw or cooked as tamago in sushi and are often found in bento lunches. Quail eggs are smaller than chicken and duck eggs.
In some countries, quail eggs are very common. In Brazil, Colombia, Ecuador and Venezuela, a single hard-boiled quail egg is a common topping on hot dogs and hamburgers, often fixed into place with a toothpick. In the Philippines, kwek-kwek is a popular street food delicacy, which consists of soft-boiled quail eggs dipped in orange-colored batter before being skewered and deep-fried. In Indonesia, small packages of hardboiled quail eggs are sold by street vendors as snacks, and skewered quail eggs are sold as satay to accompany main dishes such as soto and bubur ayam. In Vietnam, bags of boiled quail eggs are sold on street stalls as inexpensive beer snacks. In South Korea, large inexpensive bags of boiled quail eggs are sold in grocery stores. Quail eggs have Vitamin B and can help prevent heart disease and digestive disorders.
