Is a smell as good as a taste? Le Whaf, invented by French scientist and Harvard professor David Edwards, boils ingredients into a liquid, strains, then pours it into a glass cauldron. The liquid is turned into a cloud which is ingested through a straw. It is popular with dieters in Europe because inhaling the air can provide taste without calories.
Chef Norman Aitken cooks up the tasty air at Juniper Kitchen and Wine Bar in Ottawa's Westboro neighbourhood.

I'd have to be convinced.
