When I buy the cheapest peanut butters I can only describe their texture and mouth feel as ... stiff. Thick. More difficult to swallow. And not the least bit oily. Generally, displeasing in texture and flavor. By comparison a brand like Jif has a much smoother, more velvety texture that isn't super thick and goes down easier. It also retains a bit of the natural oiliness from the peanuts. Why the difference?
