I'd say about 8. I put Tabasco on a lot of things that I eat. I don't like some peppers that make my lips burn for half an hour after eating, or that burn my mouth so bad that I can't taste anything else.
If you like hot foods, try adding some cayenne pepper to a batch of store bought brownie mix. I'm terrible about measuring things, but guessing about half a teaspoon to the package. Better yet, experiment and add it to taste. I love the sweet-hot flavor and it always seems to be a hit at parties.
