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. This sort of relish is often little more than fresh corn kernels, hot peppers, and spices that are boiled briefly in vinegar. The vinegar acts as a preserving agent and also pickles the corn.
This style is sometimes called neon relish. In the Southern United States, piccalilli is not commonly served. In its place, chow-chow, a relish with a base of chopped green (unripe) tomatoes is offered. This relish may also include onions, bell peppers, cabbage, green beans and other vegetables.s a term for a mixed collection, piccalilli lends its name to several books of poems, for example, Piccalilli: A Mixture, by Gilbert Percy (1862), and Dilly Dilly Piccalilli: Poems for the Very Young (1989), by Myra Cohn Livingston.
