Im into making homemade purees for my DS. my questioon is...... How do you keep fruit purees?? i have been cutting up a piece of fruit and pureeing it evertime i give him fruit and its a pain in the butt to get the pureeer out every time, but when i puree a bunch, of peaches for example, adn store them in the fridge the turn brown within a day or so. anyone have any ideas?? i have also tried buying him canned fruit and it keeps longer in the fridge, but when fresh fruit is in season i would rather give that. can i freeze the fresh peaches or pears after pureed ??
