"Basically what happens is that you and your mom buy your own pair of Motherspoon and register onto a dedicated platform for file sharing. So when you mom cooks her recipe and uses the spoon to taste her food, the sensor laden spoon picks up the ingredients and deciphers the recipe. When put on its cradle, the spoon loads the recipe to the sharing platform so that you can access it, even if you live miles apart."
I was honestly surprised by how many times I've seen this pinned, with people wondering where to buy it. Because you can't, as it's just a concept design. In fact as aesthetically pleasing as the spoon is, I'd venture a guess that unless something happen technology wise, this will always just remain a concept. We just don't have sensor technology today that would even come close to doing what this spoon is reported to do, and even if we did the cost alone would make it out of the reach of most people.
You can read more about the spoons over at Yanko Designs, which just for the record, is a site mostly of unmade concept designs. So if you come across a pin that came from Yanko, chances are it's not a real item.
