OOHHHH!!! My favourite cooking impliment!

First, energy. About as much as a 60W lightbulb.

Almost any of the ones you find in electrical shops or supermarkets will be satisfactory.

For a single person, 1 to 1.5 litres.

Recipe?
If you are not a veggie, cheap cuts of meat; lots of vegetables, seasoning to taste and a small amount of water.

If you are a veggie, ditto but without the meat.

Also excelent for a pot roast of things like brisket etc.

Go forth and experiment!!
