Here are some definitions of the term junket:
Yes, a junket can be a trip or tour. Usually there are some strings attached. This could be that the trip of is taken by a public official at the public’s expense. Usually, these trips are to seek information—at least in theory.
It can also be a trip taken by a person who is the guest of a business seeking his/her favor.
Additionally, in a more casual manner, the junket might be a pleasure excursion include picnics or other outings.
Another lesser used definition of the word junket is a sweet, custard-like dessert. This treat is flavored with milk and rennet.
Rennet, for the uninformed—like me, is the lining membrane of the fourth stomach of a calf. If it matters, the stomach can belong to some other young animals.
