Offerings are known as "ebós", and are believed to generate axé which then gives the orixá the power to aid their worshippers. Material offered to the orixás or lesser spirits in these ebós include food, drink, fowl, and money; when animal sacrifice is not involved, a food offering is termed a "comida seca". When a ceremony starts, practitioners typically provide a "padé", or propitiatory offering, to the orixá Exu. Food is offered to the orixá, often being placed at an appropriate location in the landscape; offerings to Oxum are for instance often placed by a freshwater stream. Specific foodstuffs are associated with specific orixá; a mix of okra with rice or manioc meal, known as "amalá", is considered a favourite of Xangô, Obá, and Iansã. When placed in the terreiro, food is typically left in place for between one and three days, sufficient time for the orixá to consume the essence of the food. The ritual payment of money, often accompanying the sacrifices, is termed "dinheiro do chão" ("money for the floor"). As part of this, money is placed onto the floor and often splattered with blood, before being divided among the participants of the rite.
