For those of you that think this is a good idea for indoors...think again.

Putting foodstuff in a pot of soil and letting it rot, is much different than putting a load of foodstuff in a pile and letting it compost before use. By the time it's composted, the heat and beneficials have made an intollerable situation for the pathogens that can and will do you harm, and the beneficial bacterium have broke-down the components to a form usable to the plant.

Drying-out the ingredients does nothing to prevent rotting. Eventually it will get wet again, and rot. Plus it does nothing for breaking-down the components to a form usable by the plant.
As a general rule...if it has not been composted, it does not belong in your soil. Period.

Oh...and by the way...after using your 'tea' make sure to use care when working with it, and the soil. Some foodstuff can and do cary pathogens like e-coli and salmonella, (which you have made the perfect growing enviornment for)
