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.
So what the heck is posole? Posole is corn, basically hominy, the same kind you make grits out of. One brand of canned posole in the store here has it spelled pozole. Prepared posole is kind of like what the Senecas call corn soop (I spell it the way they pronounce it), but they don't put chile into it like we do out here in the wild west. We also sometimes do blue corn posole. It's all good. My wife's instructions. Soak posole overnight.
