I replayed SOMI:SE last weekend and at one point it got me thinking. I know it's the mark of a good adventure game wherein there are puzzles that aren't obvious, but it made me wonder what would clue somone into using yellow flower petals on the meat, other than the tradition of using everything on everything else. Other than Otis saying that the flowers are illegal to pick, there's no indication of their intended use. If I recall correctly, my parents had Prodigy at the time that I first played SoMI, so I could go online and ask the gaming forums there what I should do.
How do you remember originally solving that one or what other MI puzzles do you recall wondering about how someone is supposed to figure out the answer? (besides the monkey-wrench puzzle in MI2.)
