Do you remember your mother or maybe your grandmother saving the grease leftover from cooking bacon or other types of meat? She would have collected it in an old metal coffee can and kept in the refrigerator. Maybe [Dave Bossert is] dating [himself], but [he remebers] that vividly from when [he] was in elementary school. There was usually a wide-mouth red Folgers coffee can on the top shelf of the refrigerator that [his] mother poured grease into after cooking bacon on a weekend morning. Collecting bacon grease and meat drippings was a practice that was encouraged during World War II when conservation and rationing of goods was the norm.
