It feels like a hug from my grandma 
Awww.... pecan pie is like a hug from my grandma.
Also, fresh biscuits, with sausage or with gravy or just with butter and honey. They remind me of one of my great-grandmothers. Her homemade ones were the best thing ever!
Cornbread and chocolate skillet cake with runny icing reminds me of my other great-grandma (she loved her cast iron skillet... lol). She made the best cornbread and that chocolate cake was amazing - she made it for my birthday when she saw me. I wish I had that recipe!
Grilled Cheese and Tomato Soup (preferably made with milk)
And definitely this... I don't know where that comes from, though. It just makes me feel warm and fuzzy!
But possibly nothing reminds me of my childhood more than sopapillas with butter and honey from this crap Mexican buffet in Texas called Pancho's. I used to sit and plow through a whole basket of them after church every Sunday.

But the rest of the food there is so horrible, its hard to convince myself to go there just for the free sopapillas nowadays.

Still, its one of my fondest food memories!
