Nama chocolate vs truffle

The same ganache with and without a shell — and the shell is what decides shelf life, texture and whether it can leave a refrigerator.

Why these get confused

Both are ganache in a cocoa dusting, and a rolled French truffle is genuinely close to nama chocolate in construction. The differences are the cream proportion, the shape and — where an enrobed truffle is concerned — the shell, which changes everything downstream of it.

Side by side

 Nama chocolateTruffleWhy it matters
ConstructionGanache set in a tray, cut into cubes, dusted. No shell.Ganache rolled or piped, then either dusted in cocoa or enrobed in tempered chocolate.A dusted French truffle is very close to nama chocolate. An enrobed one is a structurally different product.
DefinitionDefined in Japan by a labelling code that sets minimum chocolate and cream proportions.A convention with no legal definition, and three different meanings by country.Nama chocolate is one of very few confection names that means a specific composition where it is regulated.
TextureSoft enough to yield on contact and melt at body temperature almost immediately. The cream proportion is high.Firmer, and an enrobed truffle has a shell to break before the centre is reached.The melt is what the product is for. A shell would interrupt it, which is why nama chocolate has none.
Shelf life and storageRefrigerated, days. A fresh dairy product with no barrier against air or moisture.A dusted truffle is similar; an enrobed one can hold at room temperature for weeks, because the shell excludes air and moisture.This is the practical consequence of the shell, and it is why nama chocolate does not travel and boxed truffles do.
Making itNo tempering required. The only difficulty is temperature control when cutting.Rolling requires no tempering; enrobing requires it. That is the step most home attempts fail at.Nama chocolate is the more achievable project, which is a large part of why it is a good first confection.

Choose Nama chocolate when

When you want the softest possible ganache texture, when you are making chocolates at home for the first time, or when the product will be kept and eaten cold within a few days.

Choose Truffle when

When the chocolates need to travel, be given as a gift, or sit at room temperature — and when a shell's snap against a soft centre is the contrast you want.

When the distinction does not matter

For a dusted, unenrobed truffle eaten fresh at home, which is substantially the same thing as nama chocolate in a different shape.
