PEANUT butter is available in a range of textures, including smooth, chunky (with small bits of chopped peanuts), natural and reduced-fat.

Homemade peanut butter should be refrigerated in tightly sealed containers and ideally used within a couple of weeks.

Turn the container upside-down occasionally to help redistribute the oils.

Commercial varieties can be kept up to six months after opening and it is best to keep them in the fridge, too.
