Boy, I sure wish I could remember when I first had Nutella. I know the story of the first time my wife had Nutella---easily a decade before we met---but I don't remember my first time!
I guess you just don't know which food you're trying for the first time will be a memory worth preserving. Which foods will matter more and more? Which will be one and off? Which will be delicious but never revisited?
I remember my first time having falafel---at a San Jose dive my mother-in-law saw on Food Network. I didn't like it. I've had good falafel since then, but it's certainly not anything I seek out. Hummus however has become an absolute staple of my diet.
Yet I have no idea when I first tasted hummus nor what I thought.
That reminds me.
I haven't tried brain yet.
Maybe on a burrito---?
