This is really gross, but Pepto-Bismol. Every time we'd get an upset stomach, my mom would give us Pepto-Bismol and I'd throw up. Was it the upset stomach or the PB? Who knows. To this day it still makes me gag.
On happier note: spaghetti sauce. Every Sunday my grandma made a big spaghetti dinner for the whole family. I still use her recipe-a little of this, a little of that, nothing measured when I make sauce.
