I don’t have a study or nothing, but I know a few other people like myself who like super hot foods and the vibe I get is that foods with capsaicin extract are edible, they’re not pleasant to eat and they lack a… rounded heat experience? It’s kinda hard to put into words. It’s sorta like “pancake syrup” vs maple syrup. Pancake syrup is sweet and sticky, but it isn’t good like maple syrup.
