For the premise of the stupid discussion to work I figured any piece of cookable physically distinguishable food object could enter the draft. Meaning dust of flour might be ok, but molecule is not. Same goes for water droplet aka fine, but water molecule is not. Also, should liquids even count? Since you set the parameters to a whole piece of cookable food aka popcorn. Which makes a cooked grain of rice okay, but a dust of flour debatable because unlike puffed rice or popped corn no one ever said "I'll just have one" to a dust of cooked flour or a crumb of bread but I'm open to discuss it.
