Lights (offal)
Lights are the lungs of game or livestock as used in cooking and butchery. Although technically offal, lights are rarely used in English-speaking culinary traditions, with the exception of the Scottish national dish haggis.
In Malaysia, slices of beef lights are coated in flour and turmeric powder, deep-fried, and sold in packets at street markets. These are a very popular snack eaten with chilli sauce and a dash of vinegar.
Bopis is a piquant Philippine dish of pork or beef lungs and heart sautéed in tomatoes, chilies and onions.
