I don't like crazy hot, but I keep plain old Tabasco and Franks on hand. I like them both. Franks for a little heat with a little extra flavor and Tabasco more for just a little heat. Neither one is over the top hot. I like that Tabasco has very few ingredients...pretty straight forward stuff.
I have a few different brands of Sriracha on hand as well, but my favorite is Harris Teeter's house brand (HT Trader Sriracha Sauce). Harris Teeter is a supermarket down south. It's not as hot as some other more traditional Sriracha, and has kind of a sweet flavor. A Tostito dipped in classic hummus, with pea size dollop of this sriracha on it = Delicious!
Years ago I got hooked on Lizano Sauce after having it on a surf trip to Costa-Rica. Not a hot sauce, more like the Costa Rican version of Ketchup I guess....it was always on the table every where we ate down there. That stuff was delicious. I used to put it on everything, but once I realized how much sodium was in it, I stopped buying it.
