This question does not have an easy answer. Food in general comforts me. That's why I love to cook and bake. But some of the things that first come to mind are:
Key Lime Pie (I have yet to make this, I have some good recipes waiting in my cookbook though)
Apple Pie with Vanilla Ice Cream
Tomato Basil Soup
All of these things remind me of good things, like, my parents, Thanksgiving, Autumn and shopping trips. This list could seriously keep going. FOOD IS AWESOME!
