You only need to follow a "recipe" if you want the compost fast. The ratio of browns to greens, how to layer, turning, etc only matter if you're trying to get compost ready quite quickly (for instance, for the upcoming gardening season). If you just throw everything into a big pile and do nothing else you'll *still* eventually get nice fertile compost... it just takes longer! You might get more of a stink too, if you don't add enough browns to your greens. (By the way, in case you don't know - "browns" refer to dry things like fallen leaves, brown paper bags. small twigs and sticks, etc, and greens are the nice ripe smelly things like fruit and veggie scraps, coffee grounds, etc)
I use a composter I ordered from my county at a discounted price. It's simple and great. It's a big plastic barrel type thing with a lid that comes off and small holes to let rainwater in. It's rodent-proof. My mother uses an old plastic trashcan with the bottom cut off. We both just throw things in. I can't be bothered to turn it worry about the ratios of stuff. I put in stuff like veggie and fruit scraps, moldy bread, coffee grounds, tea bags, egg shells, brown paper bags, cut grass, dead leaves. It doesn't smell much at all.
Good luck! It's a great way to cut down on your garbage and make some great fertile soil!
