I assume it was at the thrift store because it had the crack in it when I got it. Mike has mentioned replacing it several times over the years due to the crack. Last week I realized I'd been thinking about replacing this cracked bowl for almost 10 years now. The crack hasn't grown. It's not gotten worse. I thought there must be some sort of deep theological analogy to be drawn from this...but other than Sterilite making a good plastic product I couldn't find one.
As a bonus, it holds my fork when I need to stir & not have it fall into the batter. I wish I had more of these humble faithful vessels. If I could I'd give them golden shelves & make them masters over lesser cookware. Ha, guess what I found!
