Feeding the lwa is of great importance in Vodou, with rites often termed "mangers-loa" ("feeding the lwa"). Offering food and drink to the lwa is the most common ritual within the religion, conducted both communally and in the home. An oungan or manbo will also organize an annual feast for their congregation in which animal sacrifices to various lwa will be made. The choice of food and drink offered varies depending on the lwa in question, with different lwa believed to favour different foodstuffs. Danbala for instance requires white foods, especially eggs. Foods offered to Legba, whether meat, tubers, or vegetables, need to be grilled on a fire. The lwa of the Ogu and Nago nations prefer raw rum or clairin as an offering.
