1, lasagna is generally regarded as Italian food, but there are still different opinions about the origin of this pasta. In Britain, in the14th century, a similar food named Loseyns was once the royal meal of King Richard II of England, but this statement was criticized by the Italian ambassador to Britain. In northern Europe, a kind of Langkake food has been eaten since Viking times, and it is alleged that it may be the predecessor of lasagna.

2. Lasagna is a kind of pasta, which is characterized in that it is made by stacking large dough with many Zhang Kuan handkerchiefs, putting a variety of cheese and meat sauce on the inner layer (the vegetarian version can be replaced by spinach) and seasoning. In the west, this kind of food is generally called Lasagne or Lasagna, which is derived from the Greek word Lasanon (sputum jar) and later extended to a cooking stove by the Romans. Italians borrow this word to refer to Lasagnealforno, sometimes called lasagnealforno (lasagne in the stove), which is often accompanied by Mo Sarila cheese, Parmesan cheese or ricotta milk cheese, and many recipes add white juice as seasoning.
