I would also like to suggest that you might want to make it a point to find out if your crush has any food allergies.
I have a good friend whose sister nearly killed her off a few weeks ago by giving her a homemade recipe that was made with fish sauce... and my friend is deathly allergic to fish. And the kicker is, her sister KNOWS this... But alas.
Nothing says, "I'm interested," like sending your potential love interest to the ER... (Maybe you can then offer to nurse him back to health.)
