The best thing about the banana peppers, jalapenos, pepperocini, etc is the vinegar and how it mixes with the pepper and hotness. I love pepperocini. And I love the banana and other sliced and pickled peppers from the deli on a sub/grinder/hoagy or on a salad.
Each person has a different tolerance and likes/dislikes. And that's the way it should be. Would be a boring world if we all ate the same stuff.
speaking of brown sauce. (I don't know if I've had it [true brown sauce] before but 15 years or so ago I was on a mail list discussion list that was focused on Apple Mac OS X and related technologies -- most members had been using it since the NeXT days or way early OS X days -- and the discussion came up about bacon and how best to eat it. First, am I right to think that UK is more a "back bacon" compared to the cut used in the US? (More like "Canadian Bacon than US bacon?) Anyway, the argument came down to "brown sauce" vs BLT (bacon lettuce and tomato). It was funny and I still remember it for the humor of "arguing" about bacon -- especially when the bacon may not even have been exactly the same thing -- by a bunch of computer nerds.
