Chocolate & Cocoa
Dark Chocolate 70% in gelato
Dark chocolate 70% is a couverture made from roughly 70% cocoa (cocoa mass plus cocoa butter) and 30% sucrose. In gelato it is both a flavour base and a heavy contributor of fat and solids, so it must be balanced against the recipe's sugars and other fats rather than treated as a mere flavouring.
Balancing parameters
Per 100 g of product, verified against independent food-science sources (listed below).
| Parameter | Value |
|---|---|

| MSNF | 0% |
| Protein | 7% |
| POD (sweetening power) | 30 |
| PAC (anti-freezing power) | 30 |
Typical use: 8-20% of the total mix (toward the higher end for intense fondente styles)

Open the balancerHow to use it in gelato
Because sucrose is its only sugar, a plain 70% chocolate contributes POD and PAC almost exactly equal to its sugar load (about 30 each per 100 g), so it barely lowers the freezing point beyond the sugar it carries. Its dominant effect is fat and cocoa solids: roughly 38 g of hard cocoa butter per 100 g firms the mix and can turn gelato stiff and waxy if unbalanced. When using it in quantity, reduce other added fats and often raise dextrose or invert sugar to restore scoopability. Add it melted into the warm base for even dispersion, typically for fondente-style chocolate gelato.
Origin & background
Solid eating and coating chocolate became possible after Coenraad van Houten patented the hydraulic cocoa press in 1828, which separated cocoa butter from the defatted cocoa cake. The '70%' figure is a modern labelling convention: it states the combined weight of cocoa mass plus cocoa butter, leaving about 30% sugar. EU Directive 2000/36/EC and Codex Standard 87-1981 require dark chocolate to contain at least 35% total cocoa solids, of which at least 18% is cocoa butter and 14% non-fat cocoa solids.
