Good afternoon. I just remembered that I wanted to post a grocery buying tip. Geez, I might have read it on this thread, but I don't remember. Anyway, here it is.
All major bread companies in all of the USA use the same system. Fresh baked bread is delivered to the stores on Monday, Tuesday, Thursday, Friday and Saturday. And they all use the same color twist ties on the loaf to denote days of delivery.
Monday is blue
Tuesday is green
Thursday is red
Friday is white
Saturday is yellow
So, if you want the freshest bread, look at the color of the ties.
Thanks for the trivia!
Back at ya!
