Never heard of Cel-Ray but will try to find some. Like you, I like celery, can’t go a day without it. Chopped fine in an omelet, big pieces in soup, etc. Don’t like peanut butter or anything else in it. I was amazed to learn that many people don’t like it.
It is part of the trinity of cooking
some people hate their Mama.
Go figure
My big, doofie dog likes all vegetables (even onions) except for celery. Personally, I like celery but don’t know if I’d go for Cel-Ray. Sounds weird.
