As a condiment? Neither, assuming you mean black pepper and table salt, which I never use for anything.
Chilli peppers on the other hand, WAY different story. I love cayenne and habanero powder. Habanero and scotch bonnet sauces are my favourites, but I also love ghost and Carolina reaper sauces. As far as peppers to use in veggie dishes, I love Thai/Birdseye for heat and jalapeños for texture... mostly the thais because of high availability and cheaper prices.
I describe myself as a little dose of toxic masculinity.
