My great grandma's rolls. They tasted so yeasty and wonderful. Also her chicken soup. She made the egg noodles by hand and nothing comes close. Come to think of it, her chicken and dumplings too. Great grandma was a wonderful cook, and I'm always sad that I can barely remember her, just the wonderful food.
My greaut aunt's chocolate chip cookies. Now, Aunt Mary isn't gone yet, but because of things with my dad, I don't actually see that side of the family any more. And Aunt Mary is well into her 90s and only bakes them up for the giant family reunion. I went to her house one day when I was down in her hometown for college, and she literally just follows the recipe from the chocolate chip bag. Doesn't add the salt, mixes with a wooden spoon in a ceramic bowl and bakes just like the recipe calls for, but I cannot for the life of me figure out what the difference is and why nobody's taste as good.
