必殺技 scope of usage


必殺技 translates as "killer technique", but does this only apply to physical
fighting or does it have a broader usage? For example, can I have a 必殺技 for
making perfectly crispy roast potatoes? Would it be a natural usage?




I suppose 必殺技 can be used in a broader sense, but still in some sort of
fighting/beating context.

For example, consider someone is a expert of specific technology (e.g. a
particular technique of machine learning) and s/he uses it to solve a problem.
Then one could say 彼(女)は必殺技で問題を解決した.

I guess making perfectly crispy roast potatoes itself is unlikely to be called
a 必殺技. Rather, if it involves some techniques (right amount of oil, using
something unusual etc.), then those could be called a 必殺技 (for beating the
task of making roast potatoes).
