I'm reading an article at Quora and one answer provides the text quoted below.
If you’re dining in a formal Japanese restaurant, they serve rice last, after everything else. Dessert is…almost nonexistent. The set meals (which are expensive, costing around 20,000 to 30,000 yen on the average) also don’t include the usual dishes that we see in Japanese restaurants in other countries (you know, tempura, gyoza, gyudon, tonkatsu). Sashimi is always a staple.
I can't figure out what a staple is in this context. Nor can I judge if it means that there is or there is not any sashimi to be found. The whole sentence seems to me a bit awkwardly styled in this paragraph.
Am I missing something and if so what?
meaning-in-context
. The key to phrasing a true "meaning-in-context" question is to include your interpretation of the context, the definitions you already know or have found, and some explanation as to why you find these things incompatible. All three elements are needed for people to really understand and properly help.
