There's nothing like working feverishly to crack open a peanut knowing that your hard work will be rewarded. What lies inside the shell are some of the best tasting peanuts ever. OU Kosher Certified ATTENTION: The plain roasted peanuts are roasted and shipped without any liquid cleaning of the shells. Therefore, the shells of those peanuts will often be off color (dark brown; black; multi-colored, etc.). Those colors are representative of the soil and weather conditions in which the peanut was grown. The peanut kernel inside the shell is perfectly ok to eat and is not affected by the color of the exterior shell. In contrast, both the salted and hot and spicy roasted peanuts are subjected to a liquid curing process. The water, in combination with the salt and other spices, creates a uniform shell color by removing the dark colors from the shells.
