Yes, that is right - I used mine as a candle holder! It's surprising to see the way light comes out of the small or big holes of the grater, together creating a lovely picture of light and shadow on the wall. So now the old cheese grater with such a long history can be used again, and whether you put it on a wooden table or a slate counter top, it looks good both ways.
TIP: Use an old ashtray or a wooden block to get a bottom.
WARNING! Do not touch with bare hands immediately after extinguishing the flame - the grater is hot (own experience!).
