fizzy cider

I'm enjoying a cup of one of my favorite late fall treats: fizzy cider. Here's how you make it:
Buy a gallon of cider sometime in October and drink about a quarter or third of it. Then put it in the back of your fridge and kinda forget about it. Then in mid to late November when the plastic jug looks inflated and about to blow the cap pour yourself a glass and notice the way it fizzes. It's that easy.
