Spanish cuisine consists of a variety of dishes which stem from differences in geography, culture and climate. It is heavily influenced by seafood available from the waters that surround the country, and reflects the country's deep maritime roots. Spain's extensive history with many cultural influences has led to a unique cuisine with literally thousands of recipes and flavors. Among the multitude of recipes that make up the varied cuisines of Spain, a few can be considered common to all or almost all of Spain's regions, even though some of them have an origin known and associated with specific places. Examples include the potato omelette ('tortilla de patata', 'tortilla española' or just 'tortilla'), paella, various stews, migas, sausages (such as embutidos, chorizo, and morcilla), jamón serrano, and cheeses. There are also many dishes based on beans (chickpeas, lentils, green beans); soups, with many regional variations; and bread, that has numerous forms, with distinct varieties in each region. The regional variations are less pronounced in Spanish desserts and cakes: flan, custard, rice pudding (arroz con leche), torrijas, churros, and madeleines are some of the most representative examples.
