Another idea, which might be easier, is the old Pyrex ‘Bake-A-Round’ bread tube. You can find these on Etsy, Ebay, etc:

I would still use the Bridgford frozen dough in this.
You just can’t find little loaves of square white bread or ‘pullman’ loaves in the stores; they always have the little square Pumpernickel party loaves, but that wouldn’t go well with the chicken salad.
I’ve never seen those Pyrex dishes before. Pretty interesting. Maybe they weren’t big sellers because if you use a French mold your bread pretty much comes out round anyway :-)
All this talk about taking off crust and pretty slices of bread for sandwiches makes me think of cucumber sandwiches. I think I would have to make some of those also.
I’m trying a new batch of sourdough starter. It’s one that the website swears turns sour. And it sure smells it! If it works out I will post the recipe to your thread next week.
