Couverture block
Couverture sold as a solid mass rather than as callets. Cheaper per kilogram, harder to melt evenly.
What it is
Blocks are the traditional professional format: a solid mass of couverture, usually one to five kilograms. They are cheaper per kilogram than callets and considerably more awkward, because a block must be chopped before it can be melted and uneven chopping causes uneven melting and scorching.
For a working kitchen with a tempering machine the format is irrelevant. For hand tempering, callets are worth the premium.

Whatever it means for the couverture inside.
Working with it
Chop evenly with a serrated knife before melting. Large uneven pieces are the main cause of scorching when working from a block.

Can substitute for
- Chocolate wafersThe same chocolate in a different format. A block substitutes fine if it is chopped small and evenly — uneven pieces melting at different rates are the usual cause of an overheated batch.
