Getting Saucy

Is there a scent which instantly takes you back to a memory, the moment you smell it? My granny's canning recipe for chili sauce takes me back. It is a memory of coming home from school, opening the front door, and a savory wave of spices, tomatoes and onions hitting me. It would almost bring tears to my eyes! My backpack was as big as I was and I could barely see over the kitchen counter top. I definitely did not appreciate the art of canning at the time. Now I am lucky enough to read from my granny's handwriting, spend time with my mom, and learn this culinary art passed down through the generations.
