I've got plenty of hot sauce recipes if anyone is interested in making their own - just let me know.
The Scoville Heat Scale.
The Scoville scale is a measure of the 'hotness' of a chilli pepper or anything derived from chilli peppers, i.e. hot sauce. The scale is named after Wilbur Scoville who developed the test in 1912, for more information see Measuring Chilli Heat.
