composting cooked food and leftovers

Hi, im trying to get my compost up to a decent standard (at the moment its full of straw that i had with a delivery of manure) i keep adding green waste to it but theres so much straw that doesnt look like its rotting down atall.
since becoming obsessed with my friends and families compostable leftovers it pains me to see all the cooked food getting thrown away unused.
I know that its a bad idea to add cooked food because it attracts animals but is there any harm in me allocating an area seperate to the compost (with perhaps a sealed compost bin) to add cooked food to?
I know there are composting systems for cooked food that you add a special ingredient to because i seen them on the forums before but they looked small and expensive.

any thoughts on this?

There are a few videos on Youtube on diy bokashi worth looking at.

The completely sealed tumbler types can be used for cooked food as can ones from the council: Johannas and cones.

I took on a green cone from the Council, and, despite following the installation instructions and it apparently being rodent proof - it got infested with rats.  We hadn't seen rats in the garden prior to this time.  I am still trying to get rid of them.  I met with the recycling guy at the council and he was impressed because I have a very successful wormery and compost heaps.  He took back my findings as I was one of the first residents to take on a green cone.  They stopped advertising them to residents shortly after, so I always wondered if my experience was repeated elsewhere.

Have a look at this weeks diary as its covered there by John.
