Bomba
Timballo is an Italian baked dish consisting of pasta, rice or potatoes, with one or more other ingredients included. Variations include the mushroom and shrimp sauce timballo Alberoni, named after Giulio Alberoni, and the veal and tomato sauce timballo pattadese. The name comes from the French word for 'kettledrum' (timbale). Varieties of timballo differ from region to region, and it is sometimes known as a bomba, tortino, sartù (a type of Neapolitan timballo with rice and tomato sauce) or pasticcio (which is used more commonly to refer to a similar dish baked in a pastry crust). It is also known as timpano and timbale. It is similar to a casserole and is sometimes referred to in English as a pie or savory cake. The dish is prepared in a dome or springform pan and eggs or cheese are used as a binder. Rice is commonly used as an ingredient in Emilia-Romagna, where the dish is referred to as a bomba and baked with a filling of pigeon or other game bird, peas, local cheese and a base of dried pasta. Crêpes are used as a base in Abruzzo, and other regions use ravioli or gnocchi. In Sicily, it is typically made with pasta and eggplant.
