What the recipe doesn't tell you
Pastry Technique
Beyond basic tempering, chocolate work encompasses ganache (the foundation of truffles, tart fillings, and glazes), mousse (aerated ganache or chocolate crème), enrobing (coating centres in tempered chocolate), and decorative work (curls, shards, piping, moulded shapes). Ganache is an emulsion of chocolate and cream — the ratio determines the application: equal parts for truffles (firm and rollable when cold), 2:1 cream to chocolate for pourable glaze, 3:1 chocolate to cream for firm tart filling. Understanding ganache as an emulsion — not just 'melted chocolate with cream' — is the key to consistent, professional results.
Pouring boiling cream directly onto chocolate and stirring immediately — the cream must sit for 1 minute to melt the chocolate before stirring. Stirring too aggressively at the start — this breaks the forming emulsion. Using chocolate with less than 55% cacao for ganache — too much sugar destabilises the emulsion. Adding cold cream to rescue a split ganache — use warm cream. Folding mousse base that's too hot into whipped cream — it melts the foam. Storing ganache in the fridge uncovered — it absorbs odours and dries out. Press plastic wrap directly onto the surface.
Ganache: chop chocolate finely and evenly. Heat cream to just below boiling. Pour hot cream over chocolate, let sit 1 minute, then stir from the centre outward in small circles, gradually incorporating the chocolate into the cream. This builds the emulsion the same way a vinaigrette is built — slowly incorporating the fat phase into the water phase. The mixture should be smooth, glossy, and homogeneous. If it splits (looks grainy or oily), it's either too hot or the ratio is wrong — add a tablespoon of warm cream and stir vigorously to re-emulsify. For mousse: fold whipped cream or whipped egg whites into slightly warm (35-40°C) ganache — the chocolate must be warm enough to be fluid but cool enough not to melt the foam.
