I don't know, that last picture of the dried up pepp doesn't look to appetizing to me. I'd rather use fresh pepp, cut on the spot and done only when the pizza bakes.
I just don't find that appetizing to eat, and in reality if you buy a good quality pepperoni, you would never get that kind of oil. I buy average pepporoni, and when the pizza comes
out, there's no puddle of oil that is around each slice of pepp on the cheese.
The finished product looks pretty dried out, and hard, if I put those on a pizza going into the oven, I'm sure they would break my teeth if I took a bite, but maybe what
you are trying to accomplish here is more like a bacon bit , crunchy crunchy

Well, that's what makes the world go round, everyone has their own way of doing things, and there is no right way or wrong way.
