Lasagna, also lasagne, is both
a form of pasta in sheets (often rippled in North America,
though seldom so in Italy) and also a dish, sometimes named
Lasagne al forno (meaning "Lasagne in the oven") made with
alternate layers of pasta, cheese, and ragu (a meat sauce).
While it is traditionally believed to have originated in Italy,
evidence has come to light suggesting that a very similar meal
known as "loseyns" (pronounced 'lasan') was eaten in the court
of King Richard II in the 14th Century. The recipe was also
featured in the first cookbook ever written in England. However,
the claim is far from universally accepted, the Italian Embassy
in London particularly speaking out against it for Italy.
