Finally found these. These "Burn" flavors have been really hard to come by. I found the 1st Degree Burn about a month ago.
These are most definitely hotter than the usual "hot" Doritos. 1st Degree Burn is about as hot as I normally like to go (which is fairly hot). These 2nd Degree Burn are almost too hot. I can't even imagine 3rd Degree Burn.
1st Degree Burn is Blazin' Jalepeno
3rd Degree Burn is Blazin' Habenero
