People can be divided into three categories based on how they behave with celery.
I buy celery and when I get it home I cut it up ready to eat. Then I eat it or use it in recipes. My children eat celery.
I buy celery and it sits in the bottom of my refrigerator until I feel guilty enough to cut up what’s not rubbery and use it as “the vegetable” at dinner. Once, I used celery instead of lettuce in soft tacos because I didn’t have any lettuce. It was actually pretty good and that was innovative.
I see celery on my plate at restaurants. If it’s in soup, I avoid it. If it’s in raw spears, I eat it.
