I layer my compost because it is convenient, and because that way I can add my kitchen waste as it becomes available, usually about twice a week.
I used to keep the kitchen waste in a bucket in the garage, but it got terribly smelly, so I came up with the idea of using one of those shoe storage boxes with a cover, which cost $1.00 and I keep it in the fridge until it is full.
Wit it being cold there is no smell, so disposing of it is a pleasant task, then I cover it with plant material which I keep handy nearby.
I also keep a plastic bucket in the kitchen where I dump all left over coffee and tea, plus any water left in glasses.
I pour this bucketful over the layer of browns and I repeat this until the pile is completely full.
I do not turn or stir the pile, I just let it sit for about 6 months to a year, then I harvest my beautiful compost.
When the first pile is full I start another so I always have one pile being built and one cooking.
This system has worked very well for us.
