RE: Cinnamon swirl bread w/Crumb topping!
There was a large home-delivery Bakery Service in L A for years (now gone) It was the HELMS BAKERY. They did a wide variety of bakery products including the cinnamon swirl bread. Our Helmsman delivered to our neighborhood for over 10 years. He was like a member of the family stopping by each day.
The cinnamon swirl bread toasted up just fine, and it could absorb a large quantity of margarine once it was hot !!
