Ganache is a smooth emulsion made by combining chocolate with hot cream or another liquid. It can be formulated as a soft filling, firm truffle centre, glaze, frosting or pourable sauce. Its final texture depends on the chocolate type, the ratio of chocolate to liquid, the fat and sugar content, and the temperature at which it is used.
A higher proportion of chocolate generally produces a firmer ganache, while more liquid produces a softer or more fluid result. As a broad starting point by weight, a dark-chocolate ganache near 1:1 chocolate to cream can work for some fillings, while a firmer truffle mixture may use more chocolate and a pourable sauce more cream. These are not universal ratios: milk and white chocolate, cocoa percentage and intended storage all change the formula.
A ganache that looks oily or separated may have an unstable emulsion. Gently warm it and blend in a small amount of warm liquid gradually until smooth. If it is too fluid, allow it to cool and set before deciding whether the formula needs adjustment. Whipped ganache must be thoroughly chilled before whipping; overwhipping can make it grainy or cause it to split.
Chef’s tip: Weigh ingredients rather than relying on volume, and record the chocolate brand and percentage. This makes the result repeatable when changing chocolate or scaling production.
Food-safety note: Ganache made with cream is perishable. Cool, store and display it according to the recipe’s validated controls and local food-safety requirements.
