It's called the Aromafork. Molecule-R, a company in Montreal, is marketing it as a way to make food tastier. The premise is that if food smells better, it will taste better. The hole in the fork has a space for a scent-infused slip of paper. Bringing the fork to your mouth to eat brings the paper to your nose, filling your nostrils with that scent instead of the smell of the food.
The company currently sells 21 different aromas, including mint, strawberry, wasabi, and cheesecake. What flavors would you like to smell in your fork?
