OMG - Brockles dressing was my fav growing up too!
I remember Brockles from Dallas, too, and associate it with iceberg lettuce... like a quarter of a head. Also the Prince's drivein near the airport and the apartment buildings all the cool peope lived in -- that were right under the flight pattern out of Love Field, so they were horribly noisy. Can't imagine why it was so cool to live there.
Guess I'll have to share some with ya, huh? If I get a new stash, I'll mail you some. I bought all the store had, just 4 jars, but I haven't gone to another HEB to find more (yet). FReepmail me if you want me to.
BestMaid has a website for ordering their mayo and some of their pickles (I was delighted to find out they also own Del-Dixi, excellent pickles) but doesn't even mention the "sandwich spread" at all! And the word "Brockles" never comes up, either - but it's as close as it can possibly be to the same thing.
I believe it's listed as Dalton's BestMaid Products online.
