About a week ago, from the great Wal-Mart was acquired "Thai Kitchen" brand coconut milk. It had coconut milk, xanthan gum, and soy lecithin (emulsifiers). Tonight, that can was openned, and it looked like whipped cream, only with lumps the size of grains of sand. The smell was faintly of coconut and somewhat nasty otherwise.
On the underside was the date 05266, which is what, October 3, 2005.
I should have taken a picture, but I was instructed to rinse it down the drain prior to Rachel getting home.
