Choosing chocolate for cooking
The right chocolate depends on what it has to do — coat, set, melt into a batter or hold its shape — and those requirements pull in different directions.
If you read nothing else
Match the chocolate to the job, not to the price. Couverture for coating, ordinary dark for baking, chips only where you want distinct pieces, and never compound where the chocolate will be tasted on its own.
For coating and moulding
Couverture, because its high cocoa butter content gives low viscosity, a thin even film, clean mould release and a hard glossy set. An eating bar used for this will pool, set soft and fingerprint, and no amount of technique will fix it. This is the single most common materials mistake in home chocolate work.
For baking
An ordinary dark bar of a stated percentage, chopped. Establish what the recipe assumes first: a recipe built on unsweetened chocolate and made with a 55% bar gains a substantial amount of sugar it did not account for. Chocolate chips are formulated to hold their shape and are the wrong choice wherever the chocolate is meant to melt into the mixture.
For ganache
Any good eating chocolate, with the ratio set by the type rather than by preference: roughly 2:1 chocolate to cream for dark, 3:1 for milk, 4:1 for white. Using the dark ratio with milk chocolate produces a ganache that will not set, which is a materials problem presenting as a technique problem.
For decoration
Compound is the correct choice, not a compromise. It sets hard and glossy without tempering and tolerates a warm room. Where the chocolate is a thin decorative element rather than something tasted on its own, its poorer melt behaviour costs nothing.
For drinking
Real chocolate rather than cocoa powder if a rich result is wanted, because the cocoa butter is what makes the drink viscous. Cocoa powder makes a thinner drink and needs slaking to a paste with cold liquid before hot liquid goes anywhere near it.
