I went to the store on Friday, two days before Purim, to buy ingredients for hamantashen. The problem was, there were too many flavors of filling: strawberry, blueberry, apricot, and many more. I wasn't sure which one to buy.
Then I noticed that there was a can of mon filling. I know that there are a lot of special halachot related to mon, for instance that you can't leave it overnight unless that night is Shabbos. But the can had a hechsher and it was on sale in a Jewish store, so I knew all those halachot were followed and it would be ok to serve on Purim night, Motzaei Shabbos.
I thought, "Great! Now I can just buy that, and the hamantashen will taste like whatever I want!" (As long as it's not cucumber, melon, leek, onion, or garlic, but who ever heard of hamantashen in those flavors anyway.) (Rashi Bamidbar 11:5)
But it didn't work! I had in mind that the hamantashen should taste like several different flavors, but their taste always stayed the same. I didn't like the taste much, but I had to eat them all before morning anyway to avoid the issur of leaving mon until the morning.
What did I do wrong? Why didn't they taste like whatever I wanted?
