congee theory

I didn't even know it existed until today. I was chatting to my sister-in-law about cooking dinner last night, the staple dish happened to be congee (rice porridge or even jook to some). Anyway, I explained that I shouldn't be dining with her this evening as I had some left over congee in the fridge. Then she said, "Haven't you heard about the congee theory?"
"What congee thery?"

Well, let my englighten you my friends, cause that's what I'm here for.

The congee theory is that you should always cook enough congee only to be consumed for one meal. You can never have left over congee because if you leave it over night and eat it the next day, it'll give you stomach gas. In other words, it will lead to passing wind like there will be no tomorrow. It's got to do with the starch and some kind of fungus breeding for keeping the rice in that state for more than 24 hours or some shit like that.

Now that I have shared my new found wisdom with you, anyone for deep-fried ghost?

If you are a member of my family who is living in Madrid reading this, the deep-fried ghost will become a soggy mess no matter how fast DHL can deliver. MYO!
