I never saw this until moving to Japan. Everywhere I’ve dined in with pizza gives tabasco. I tried it and I like it. Especially for vinegar-based or otherwise more acidic sauces, it cuts through the fattiness from the meats and cheese and brightens things up. I also like spicy things (we frequently do habanero hot sauce these days). I think maybe a splash of something like white wine vinegar might be nice if someone isn’t into the heat.
