Scotch Bonnet! That is the best pepper in terms of taste - it is so unique - it is hot, but not on the level of reapers.
Reapers seem to be the standard "go hot" stuff, but they do have a distinctive flavour.
I have been making hot sauce in the slow cooker, and I have about 4KG of chilli in the freezer from my plants. :|
My plants are still producing and we're about to come into Summer here in Australia. Winter didn't kill them, and I am very glad, but I am wondering where the hell I am going to be putting all the sauce that I make.
Reapers are hot, but a little goes a long way :)
