Couverture

Couverture

Couverture is chocolate with a high enough cocoa butter content to be tempered, so it sets hard with a snap and a mirror gloss and releases cleanly from a mould.

What separates it from compound

The dividing line is the fat. Couverture uses cocoa butter, and EU labelling rules put a floor under the word: at least 35% total dry cocoa solids, of which at least 31% cocoa butter. Compound coating, sold as candy melts or cooking chocolate, replaces most of that cocoa butter with a vegetable fat.

The consequence is practical. Cocoa butter crystallises in several forms, only one of which gives snap and gloss, so couverture must be tempered. Compound has no such crystal behaviour, which is why it can be melted and used with no technique at all, and why it never quite snaps.

Why bakers pay for it

The extra cocoa butter thins the melted chocolate. Lower viscosity means a thinner shell when enrobing or moulding, so a bar of couverture covers more surface than a bar of a cheaper chocolate, which offsets part of the price difference.

Untempered couverture still tastes fine. It sets soft, dulls, and blooms grey within days, so it belongs in a ganache or a batter rather than on a decoration.
