If the process has a normal distribution, 99.7% of the population is captured by the curve at three standard deviations from the mean. Stated another way, there is only a 1-99.7%, or 0.3% chance of finding a value beyond 3 standard deviations.
Relish is one of them. The most traditional corn relish traces its origins to the South, particularly Louisiana.
