Iron,
I’m a bit of a snot about food and such, but it really depends on what you’re eating. Sriracha is great, but hardly goes well with mexican food…I also find it a tad sweet. Great for asian flavors, not so good with others, IMO.
Anyway, a good tactic is to familiarize yourself with the relative heat level of the different peppers that are out there and then read the label. I too, find tabasco too vinegary.
In order to get truly hot food, I’ve found I have to argue with the waitstaff. When the silly round-eye asks for “Native Thai Hot,” I invariably get something too sweet and tepid. The local Thai joint near my house, however, has finally figured it out. We all have a good laugh about it because the waitress we usually get always goes back and we can hear her arguing with the cook in Thai over my order. Or maybe they’re just making jokes at my expense. I don’t speak Thai.
There are a lot of crappy sauces on the market, and most specialty sauces have a lot of sugar in them to appeal to the American palate, which has degenerated thanks to a diet of processed foods and gustatory timidity. Cholula has a great flavor, but isn’t really “hot.” Texas Pete, Frank’s, Durkee, etc all suffer from a sort of boring similarity and no real heat. Great for New Orleans style food…
For Indian food, try this: Mix equal parts minced green chili pepper (your choice–I like the little green thai bird chilis. Hot, but not Scotch Bonnet/Habenero hot…) and ginger. Serranos are ok in a pinch, but I use Jalapenos for company. Add a quantity of salt, to taste a bit of vinegar or lime (I like lime) a tiny bit of vodka (certain flavor compounds in several foods are alcohol soluble, but will not dissolve in water) and a small bit of a neutral-flavored oil (capsacin is an oil–like dissolves like…). Stir to moisten (the whole thing should glisten with a SMALL bit of liquid in the bottom) and store the remainder, tightly wrapped/covered in the fridge.
The fresh ginger will brighten the dish and the peppers are um… hot.
One last caveat–chile peppers have different names from store to store and region to region. Learn to identify them by sight, vice name.
