cantabene--Oh, pepper can certainly suppress flavors, especially if it's been sitting in a bottle forever. But red pepper actually isn't like other peppers in the way that it isn't necessarily as hot in temp., but sweeter in a way. I use it in everything because I grew up mostly eating spicy foods, which is not to say hot, but full of spices.
Here in Minnesota, the pallet is bland, bland, bland--mostly Swedish, Norwegian dishes and really poorly prepared classic American. Ketchup is spicy here and more than half the population is allergic to spices, tomatos and onions.
But you know, they say you are what you eat, so maybe that is another reason why some of us choose to digest so much cheese and so many spices.
