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.

Commonly confused with

  • Callets and pistolesThe same chocolate in two formats. Blocks are cheaper per kilo and must be chopped; callets melt evenly and can be weighed for seeding.

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.
