Step-by-step explanation:
The dessert created by Escoffier in honor of an Australian opera singer is named after Nellie Melba. This dessert, known as Peach Melba, is a classic creation that combines peaches with vanilla ice cream and raspberry sauce. Escoffier was inspired to create this dish in the late 19th century to honor the renowned soprano Dame Nellie Melba, who was one of the most famous singers of the Victorian era.
