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.
No they are NOT the same. Corn flour is the entire corn kernel milled into flour. It contains protein and fat as well. Corn starch is just that - starch. It is chemically seperated from the protein and other components of corn flour. However they can sometimes be used interchangeably, especially in soups and stews. But for breading and deep frying, you cannot substitute corn starch for corn flour.
