Cayenne is possible, I hope that's the verdict.
I have a really gnarly one.
The ones that look like alien waste are hot fire.
I don't really know what they "taste" like, unless fire is a taste.
Alien waste? Do you mean blistered like a Carolina reaper?
If so yes those are serious shit, I am growing some for an old Vet I know. He can't taste spice in my opinion so he wants me to grow him stuff to test his limits.
Some of the hot hot peppers really do have great flavor, best I have had is Peach Ghost Pepper, great flavor that you get first and then undeniable heat. Citrus sweet aroma that makes great salsa and probably lots of other stuff.
Grew some last year but not this year, have a few roasted and dried though.

Looks like you are into a nice tasty tomato harvest, and that is a good thing.
Was just thinking of making a marinara meat sauce with ours which just came on in the last few days and are now abundant.
Tried a San Marzano today at the Vet's garden and it was amazing, gonna grow some next year. Small sweet and I can see why they are popular. They grow in clusters which is interesting.
I recommend anybody giving them a try.
