Over the years I've accumulated some of these baking tubes and have, until recently, been a bit perplexed at how to use them. I searched the Internet with unacceptable success. However, on a regular basis, I receive the catalogue from the King Arthur people. It's called The Baker's Catalogue, Inc.
In the copy I received on Saturday there was a recipe for Sandwich Bread Canapes
using baking tubes. Yeah! Now I have a trusted group of bakers to help with my dilemma. I'm going to try the recipe this week.
