I love fruits and with two kids, I buy lot of them too. But it is always hard to figure out if the fruit is going to be sweet and juicy. Today morning, before coming to work, I thought I would eat some grapes and I put the first one in the mouth and it was very sour. I wish there was a way to check sugar level in fruits. If we can check blood sugar :), can we not check fruit sugar? if somebody had a device for that I would love to buy one. Maybe then all the stores would keep same fruits sorted by their sugar level and I would not mind paying some extra for the sweetness either.
