I wondered if anyone knows the trick to keep apple slices crisp and from changing colors? I often don't have the strength in my hands these days to cut the apples. So, when I do or when I have someone around to do it for me, I'd like to cut them up and store them so I can have some whenever I want. I'm actually doing this with all my fruits and veggies. But, apples always turn brown and get kinda mushy when you cut them up and store them in the fridge. Thanks.
