Ganache Ratio Calculator

White chocolate contains no cocoa solids and a higher sugar content, which interferes with the emulsification and setting process. It behaves more like a flavored fat than true chocolate. To achieve the same set texture as dark ganache, you need approximately 50% more white chocolate. Milk chocolate, with its intermediate cacao content, requires about 15% more.

Heat cream to just below boiling — about 85-90°C (185-195°F). At this temperature it has enough energy to melt the chocolate and emulsify the fat. Do not boil the cream, as boiling evaporates water and can destabilize the emulsion. Pour the hot cream over finely chopped chocolate (smaller pieces melt faster and more evenly) and let it sit for 2 minutes before stirring.

Broken ganache (where fat separates) can usually be rescued by adding a small amount of warm cream or warm water (one teaspoon at a time) while stirring vigorously. Grainy ganache is caused by chocolate that overheated and seized — add more warm cream and use an immersion blender to emulsify. Prevention: chop chocolate finely, use cream at the correct temperature, and stir from the center outward without introducing air.

Yes. Medium (1:1) or pourable ganache, once cooled to room temperature and then refrigerated until firm (at least 2 hours), can be whipped with a hand or stand mixer until it lightens in color and doubles in volume. Whipped ganache makes an excellent frosting with a lighter texture than standard ganache.

Ganache keeps for 2 weeks in the refrigerator or 3 months in the freezer. At room temperature, ganache made with dark or milk chocolate can safely sit for 2-3 days (the sugar and fat create an inhospitable environment for bacteria). White chocolate ganache is less stable at room temperature and should be refrigerated.

Yes. Flavor additions include: liquors (1-2 tablespoons per 400g batch), extracts (1 teaspoon), infused creams (steep herbs, spices, or tea bags in hot cream for 15 minutes, strain, then use as the cream component), and citrus zests (added to hot cream and strained). Oil-based flavorings should be avoided as they can break the emulsion.

Ganache is an emulsified mixture of chocolate and cream that sets firm at room temperature (firm) or to a thick coating (pourable). Chocolate sauce typically contains water, sugar, and cocoa or chocolate, and does not set at room temperature. Ganache has a richer, creamier mouthfeel due to its higher fat content.

Yes, with some adjustments. Full-fat coconut cream (not coconut milk) is the most reliable substitute — use the same weight as dairy cream. Oat cream and soy cream also work but may produce a slightly less glossy result. The ratios in this calculator apply to dairy and full-fat coconut cream. Lower-fat plant creams may require increasing the chocolate fraction by 10-15%.

A small addition of unsalted butter (about 5% of total weight) increases the gloss and richness of ganache without significantly changing its texture. The milk solids in butter also contribute a subtle caramelized flavor note. Stir butter in at the end after the ganache is fully emulsified and has cooled slightly to about 35-40°C (95-104°F).
