moderate. i like spicy things but i find a lot of the spice that people chase - extremely high amounts of capascin - is frankly not only overpowering but boring. spices are a whole realm of condiments. step away from the weird habanero cultivars made by people who view the scoville number as a high score, and step into the wonderful world of indian tumeric, sichuan peppers, mild unripe spanish padrón peppers...
damnit answering this made me crave. going to go get some sisig now (keystone spice: siling labuyo, a Capsicum frutescens cultivar, same species as the peppers they make tabasco sauce out of, though thai birds eye peppers are often used instead)
spices are a wonderful world of complex flavors and tastes and limiting yourself to chasing What's The Hottest is booooorrrring. and doesnt even work for many dishes!
