Any tin can will do. The problem is matching the quantities of the recipe to the size of the can! And don’t believe the stuff about filling the can only 1/2 - 2/3 full. It doesn’t rise much because you’re only using a scant amount of baking soda.
I’ve never made it, because I’m not really crazy about it. But I’d like to try other quick breads in cans; so the tomato cans will work. (I like the idea of ‘round bread’ - looks nice cut-in-half for little tea sandwiches :-)
