I love hot sauce of any kind on pizza, it takes on a whole new flavor. It's much better than any dried pepper.

I use a lot of Cayenne powder / flakes. I also really like Thai Hot's, and Lemon Drops, and even habaneros, but, any relatively thin walled pepper is a good candidate. :-) I dry most kinds I grow, but, some of the thicker walled ones find the freezer.

If you're looking specifically for an Italian hot drying pepper...sorry, I can't help, but, hopefully someone else here can.

Espelette is a good medium heat pepper that dries well. Cayenne is usually the standard one for flakes. I agree with Tsheets about Lemon Drop...it makes an excellent dried powder. I find it to be about as hot as Cayenne. I like it sprinkled on bagels with cream cheese where you can really pick up on the subtle citrus flavor.

If you live near Walmart, check out their produce section for dried chiles. They usually carry bags of Guajillos and Japones, the latter being a bit hotter. I collected Japones seed from a bag(shame on me but there were holes in the bag from which seeds were dropping)and grew some out. Nice plants with clusters of upright pods about 3" long.

I'm with T Sheets - cayenne or Thai. N+Both are easy to grow and easy to dry, and taste great on pizza among many other things.

I dried and ground some of my jalapenos, they have a very nice jalapeno flavor. I did have to add some heat back into them, because I removed the seeds when I was cutting them up for drying.

Gotta try some smoked chocolate hab powder. Once you do you will never look back:)

I went with the Thai Hot.
