What about of Peanut Butter?
Peanut butter is a food paste made primarily from ground dry roasted
peanuts, popular in North America and the Netherlands. It is mainly used
as a sandwich spread, especially in the iconic peanut butter and jelly
sandwich. The United States and China are leading exporters of peanut
butter.
Although the peanut has a long history, having been found in Peruvian
mummy tombs, peanut butter is a relatively young food.
In 1890, an enterprising physician, Dr. John Kellogg (of corn flakes fame),
created peanut butter as a healthy protein substitute that was easy to
digest for patients with no teeth. The manufacturing process was mechanized
by George A. Bayle, Jr., and a patent for a peanut-butter machine was
issued to Abrose W. Straub in 1903.
How Select Peanut Butter?
There are many choices when selecting peanut butter：
Peanut butter is available in smooth, chunky (with small bits of chopped
peanuts), natural, reduced-fat, no sugar added, and even swirled with
jelly for those time-challenged consumers.
Commercial varieties are usually a blend of ground, shelled, roasted peanuts
mixed with vegetable oil (usually hydrogenated) and a bit of salt. Some
varieties also contain sugar and additives as stabilizers to prevent oil
separation and to also enhance flavor.
Natural peanut butter normally contains only peanuts and oil, and will
often separate requiring stirring.
How store Peanut Butter?
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.
Natural peanut butters should be refrigerated after opening and can be
kept up to six months.
Commercial varieties require no refrigeration, can be kept up to six months
after opening. Unopened jars can be stored up to one year in a cool, dark
location.
Peanut butter is not a good candidate for freezing.
