Notes
1 tablespoon of fresh lemon and or lime zest can be used in place of dried peel.A glaze can be made with 3 tablespoons powdered sweetener and enough lime juice to get the right consistency. This will provide enough glaze for a drizzling on top. Cream cheese can also be added to the glaze.Allow bread to cool completely before slicing.
