I'm ok with veggies but I'm horrible at picking the best fruits at our supermarket! Watermelons are pretty easy. I just tap to hear hollowness and try to find one that feels heavy for its size. But I can't for the life of me pick out a good pineapple or cantaloupe! They're always too ripe or not ripe enough (usually the latter).

Do you have any tips for picking the best fruits or veggies?
