I have to say that Angostura bitters and soda is my favorite drink....other than tequila. If you have an upset stomach...its the solution. Bitters in chile? Hmmm. I prefer more natural chili flavor.
Cheers, TB.
Lemon Lime & Bitters is a very popular drink. From my limited experience in making sauces limes seem to feature in the ingredients. I guess youd have a "chilli lime & bitters"!
