Tabasco isn't hot. I don't like it anyway, because it has too much vinegar in it, so it more often spoils the taste of food. (Edit: turbo beat me to it!) The tastiest hot sauce I ever had was one that someone I knew bought when he visited one of the Carribean islands (I don't remember which one anymore). It was something homemade. We had a big bbq with chicken wings made with that sauce on them...mmmmmmm, yummy yummy! It had a real kick to it, but not so much that you couldn't taste the flavor.
That's really a challenge, finding something that has both heat AND flavor. In order to get the heat, too many people just start subtracting other ingredients and adding more of their flavorless hot sauce, so there's no flavor left.
I had a very tasty cooking accident not long ago. I was bbq'ing some chicken quarters, and put on a dry rub first. I decided I wanted it spicier...the dry rub is a little spicy, but not much...something that all but the most sensitive can eat. I have a big container of chipotle powder, and tried to sprinkle a little on, and oops, too much poured out. The chicken was fully coated in it. I grilled it, added some homemade bbq sauce (recipe shamelessly stolen from my boyfriend), and nearly choked on the first bite not expecting it to be quite that hot (I've used the chipotle powder before, and it was never very hot...I just never used that much before). But, once I knew to take smaller bites, and got past the skin and into the underlying meat that the flavor had really cooked through into (too often all the flavor just stays on the skin), it was REALLY tasty. That nice smoked chipotle taste was wonderful, and a pleasant kick.
