If it works for pineapple...
...it doesn't necessarily work for blueberries. There's nothing bad
about it, but blueberries just don't hold up as well as pineapple as a topping. Their flavor's not as strong and they might as well not be there. Maybe they don't have the sharp acidity that makes pineapple stand out.
I don't know how they are all facing the same direction. I just tossed them randomly. My strange luck again.
The recipe was simple: Preheat oven to 500° F., oil the pan with avocado oil, spread out the dough, lay the sauce, sprinkle with ground black pepper and green chili flakes, cover with shredded mozzarella, lay the pepperoni, cover with more mozzarella, lay the blueberries, and bake for 10 minutes.
