My mom LOVES nuts. So my whole childhood almost all baked goods had nuts added, brownies, chocolate chip cookies, banana bread, fruit cake, and so on. In fact, she would add double the amount called for! And her favorite nuts are pecans and walnuts, black walnuts in particular. Sadly for me, the two nuts I don't much like are pecans and walnuts. All other nuts are okay in say, mixed nuts, or some kind of salty snack. But NOT in sweets!
I think the world is evenly divided on this.
Half says, "Ah, too bad, this doesn't have nuts in it!"
The other half says, "You wouldn't go and ruin a perfectly good (brownie) by putting nuts in it, would you?"
One other thing people are divided on is chunky vs. smooth peanut butter. For me, I much prefer smooth peanut butter, but some folks just gotta have that extra crunch.
Like they say, sometimes you feel like a nut, sometimes you don't!
Individual taste is a wondrous thing. I would hate for all of us to be clones. Life is more interesting that way.
