Escalope

An escalope, also scallop in the US (not to be confused with the shellfish), is traditionally a piece of boneless meat that has been thinned out using a mallet or rolling pin or beaten with the handle of a knife, or merely butterflied. The mallet breaks down the fibres in the meat, making it more tender. The meat is then coated and fried. The thinner meat cooks faster with more moisture loss.
