China chilo is a dish of stewed mutton from 19th-century English cuisine. Stewed with onions, peas and lettuce, the mutton is served in a dish surrounded by a border of rice. Scholars believe the term China in the name alludes to this oriental ingredient, but the meaning of term chilo remain a mystery. The dish is said to be based on a Chinese dish that 19th-century sailors described upon their return from the China Seas. Food historians speculate whether creative Victorian cooks substituted lettuce for bok choy and peas for bean spouts.
