You may remember from two or so years ago where a Japanese specialty retailer debuted the square watermelon for Christmas (yes, they celebrate Christmas there, mostly as a commercial holiday). Nothing artifical, the melons were simply grown in wood frames. Well, now one of the British grocery giants, Tesco, has coopted the idea and is about to debut them in stores. The only big differce will be the price. Whereas the Japanese versions cost about $75, Tesco’s will only be about eight bucks (a small price to pay for a melon that won’t roll around crushing groceries on the car trip home).
