Apples are a staple in my house now. I love eating green Granny Smith apples with peanut butter. Any kind of apple is pretty versatile, but the Granny Smith is my favorite. It's tart, so it's perfect for mixing with something sweet. They hold up better, too. However, when I was a kid, my apples were always Red Delicious.
Mom always greeted us with a big apple when we got home, at least the way I want to remember it. She would cut it for me and I would put some salt on it (not anymore), and I would munch that apple while watching the Brady Bunch. Happy memories; happy food. At Thanksgiving, I made a Snickers trifle with Granny Smith apples, and it was great. Of course, I can't eat them that way every day!
