Question: how hot are peter peppers?
Answer: Peter peppers range between 5,000 and 30,000 Scoville Heat Units (SHU) on the Scoville Scale, which is quite hot. At 30,000 SHU, this is 6 times hotter than the average jalapeno pepper. It is more on par with the serrano pepper, which has some very good heat for cooking and sauce making.
