Ansai

Ansai [淤羞; あんさい] are offerings of food laid out at Kiren temples in Kanton. They are also known by a variety of dialectal and regional names, such as jūsho, kansho, kansai, shoi, and more.
Many traditional festivals and ceremonies involve the offering of food, particularly of the expensive or well-made variety, to the altars of temples or shrines. Although temples would often receive more significant edible offerings, many customarily leave small vegetable fritters known as bashi at shrines around their local area.
Food offered up could range from rice, seafood, herbs or seasonings such as mint and ginger, local specialities, seasonal foods, or sweetmeats. Once all of the offerings had been gathered up at the end of a festival, a large feast was traditionally held, during which everyone in a village would eat the blessed food together and give thanks to the gods. This would reinforce the bond between humans and spirits, and gain the gods' favour and protection. This event was known as tamashiru, and still continues today in some parts of Kanton.
