I did it again, I have confused another pair of ingredients when shopping at the store. This time I purchased cilantro when I wanted parsley. I could have easily noticed my error in advance because I strongly dislike the smell and taste of cilantro, but I had relied on a sign above the display and did not investigate on my own. Also, the tie around the cilantro bunch was properly labeled so I know to check that next time. These ingredients can be used as a substitute for each other in some recipes.
Last time I remember purchasing the wrong ingredient was in high school. While shopping for taco ingredients I picked up cabbage when I wanted a head of iceberg lettuce. There are subtle differences between these two and they are not typically individually labeled. For tacos I wouldn’t mind the substitution, but my father was les than pleased with the idea.
