To prepare pull off any tough outer leaves from the cabbage and discard. Cut in half, then remove the hard inner core. Rinse each half and cut to the size of slice you like. Some folks cut it in large cubes and others like it sliced. Overcooked cabbage can be smelly due to the sulphur compounds in it. This sulphur is often what children pick up on and they find it off putting. Try adding a piece of butter to the water when you are boiling the cabbage to counteract the sulphur and change the taste but not the goodness.
