2 Different things, I will explain as simply as I can... you got a peanut, you can make it into chunky peanut butter so it maintains some of its original integrity and "chew" (or mouthfeel as they call it in the culinary world) or, you can pulverize the hell out of it to make it like "creamy" peanut butter -- simplified example, but yes, its ok to GROUND A+ beef and make it into a burger, but to stick it into a blender till its homogenous and take away its texture, not so good... hope this helps, but the same thing goes for everything except maybe pudding or "cream of" soups :-)
