Salo is often cited in European humor as a stereotypical staple of Ukrainian cuisine, analogous to the association of cheeseburgers with the US and bratwurst with Germany. The beloved traditional dish consists of smoked or salt-cured slabs of pork fatback, often flavored with paprika or garlic. It contains little to no meat and is usually consumed raw. It can also be rendered for use in cooking or chopped up for use as a condiment. What salo-based dish was invented as a joke? Discuss
