OH boy!! I like this thread.
I keep about a dozen or so hot sauces in my house. Most are the very, very hot variety such as ghost pepper or Habanero. We have a market here in Cincinnati called Jungle Jim's. They keep about 3 to 4 thousand different sauces and rubs on hand. I am lucky enough to live 5 minutes from there. I'll try to get a picture tomorrow. I am going there tomorrow to see if they have that Kumano Sauce mentioned above.
As much as I like trying the different Xtra hot sauces, my favorites are still the classics like Tabasco, Louisiana, or Cholula. I like flavor as much as I do heat.
I used to carry Tobasco in my flight bag to put on the various tasteless foods I would encounter in my travels. One problem I kept having was the lids kept cracking and the sauce leaked out into my bag. So I decided to look for something different. I settled on dry rubs because they did not leak and soil my bag or the contents. At first I just carried your garden variety red pepper flakes. The kind you would use on Pizza. That worked OK, but I wanted something with better flavor and a bit more heat. I finally found a product called "Habanero Heat wave shake" made by a company called Tom's Garden. It has good flavor and heat. In addition it does not leak into my bag.
Here is a good story you may like...
My father, six months before his passing came to visit me. One evening at dinner dad was looking at my collection of hot sauces. I usually keep three or four on the kitchen table. He took some and starting pouring it on to his hot dog. "dad" I said "that is very hot". he kept on pouring like it was Texas Pete or something. I spoke a little more louder "Dad, That is really hot". He looks at me and say "I know son". I decided (and remembered) that my dad is one of those people who has to learn things on his own. My son, who was 10 at the time was very aware of what was about to happen, He ran upstairs. So dad bit down on that hot dog...then he began to turn red and spat out that sauce laden wiener. He must have drank 10 gallons of water. Of course after I made sure he was going to live, I laughed my butt off at him. I of course shared this story with my sisters who in turn teased him as well. He passed about six months later. I was told that he would never touch hot sauce again, not even the weaker stuff.
