Chili powder is a confusing spice. This is because the spelling often dictates what you’ll find on the ingredient list.
With two specific varieties of chili powders included in my list, I can't miss including one that you surely have in your pantry: regular chili powder. But I want to emphasize that you must only use it as a substitute for Hungarian paprika when you have no other options.
Having said this, something as beneficial as capsaicin does not come without any trade-offs. Producing capsaicin takes a lot of energy, which is why some peppers are not spicy. In some cases it makes more sense to make a lot of fruit with less or no capsaicin, thus producing more seed, and getting offspring by overwhelming predators and plagues by sheer volume.
Think of capsaicin as a powerful defence mechanism plants have developed to survive. The key about capsaicin is that it does not affect all species of animals or fungi. This is a brilliant evolutionary development that makes the existence of capsaicin twice as beneficial to the plant.
