Canned Asparagus
Asparagus is more expensive than other vegetables, because much of the harvesting and preparation during processing is done by hand. The spear, or stalk, consists of the stem and head (tip).
There are two types of asparagus: green and white. Green asparagus is canned or frozen; white asparagus is canned. White asparagus is a delicacy, produced by mounding earth around the plants so that the stalks develop entirely underground.
Sometimes canned asparagus is packed in glass jars with a note on the label that a color preservative (stannous chloride) has been added. Some canned asparagus spears may have shattered heads, because asparagus is such a delicate product.
