Nyorog is a tradition for the Betawi people to welcome the holy month of Ramadan. Activities carried out in the Nyorog tradition are sharing food parcels to relatives and families who live far apart. This is because the Betawi people in ancient times had places to live far from one another. At that time, one house to another was bordered by a forest or a large garden.

The food parcels sent in the Nyorog tradition are kind of pastries, or raw food ingredients, namely sugar, milk, coffee, syrup, rice, milkfish and buffalo meat. Sometimes the nyorog parcels are Betawi specialties that are put in a hamper, for example, sayur gabus pucung.

This tradition is carried out as a sign of respect from younger people to older people. Usually done by young people or newly married couples to their respective parents.

According to some sources Nyorog comes from the traditions of ‘Sedekah Bumi’ and 'Baritan'. Both are traditional ceremonial rites which are a reflection of human interaction, the environment, and belief in the creator.

Before Islam entered the archipelago, especially in Java, people often brought food for offerings which would be presented to Dewi Sri, a symbol of prosperity. This activity was an expression of gratitude to the Goddess of Prosperity.

Then after the arrival of Islam, the Nyorog tradition was carried out as a symbol of respect and friendship to elders or respected village elders. Another source states that the Nyorog tradition has been practiced by the Betawi people since the 1800s. The Nyorog tradition was introduced by the Wali  when spreading Islamic teachings.

The Nyorog tradition is not only carried out to welcome the month of Ramadan, some is done to welcome Eid or Lebaran. The Nyorog tradition can also be found in wedding ceremony processions. Usually, the groom's family comes to the bride's family before the proposal with a sorogan or a food parcel.

Nyorog or sorogan can also be interpreted as a binder or 'bribe'. In other words, this sorogan functions as a binder for the bride to be willing to be married to the bridegroom.
