Yield: This recipe makes 48 crackers from one 9-by-5-inch loaf. The exact count will vary slightly depending on how evenly you slice.
Technique: The loaf must be fully frozen before slicing. A partially chilled loaf will crumble and won't give you clean, thin slices. Use a sharp serrated knife and work quickly.
Measuring: Pack the brown sugar firmly into the measuring cup. Loose brown sugar will under-sweeten the loaf and affect how the batter holds together.
Storage: Store at room temperature in an airtight container for up to one week. They actually get a little crispier as they sit. For longer storage, freeze in a zip-top bag and pull out what you need.
