Living in the country we can get away with a lot of stuff that might be
frowned upon the in the city. When I clean a pot in which I have cooked
porridge or rice I usually used a brush on the pot. I then pour the
contents through a strainer and dump the lumps into the compost pail, or
go outside and dump it into the garden. I water the plants and give the
the soil some composting material at the same time.
