I mean, I don't care for pineapple on pizza but I can see why such a thing would be invented in a place like Hawaii.
But let me risk a negative response and say 'bacon'.
I know what you're going to say! Everyone loves bacon, bacon is good with everything, blah, blah, blah. Mixing bacon with everything makes all that stuff better.
And you're right.
And yet.
While putting bacon on your cheeseburger may improve the cheeseburger, the question I ask is this: Does putting bacon on your cheeseburger improve the bacon. I say nay! Leave the bacon aside, enjoy the 'pretty good' cheeseburger and then consume the bacon unblemished. Mix nothing with bacon, lest you risk making the bacon worse.
Bacon is best pure.
