Salt in gelato
Salt (sodium chloride) is a pure crystalline mineral used in gelato in tiny amounts as a flavor enhancer. It adds no sugar, fat or sweetness, but it has the highest anti-freezing power of any common mix ingredient.

Salt is dosed at a pinch level and works mainly as a flavor enhancer: it rounds sweetness and lifts the perception of caramel, chocolate, pistachio and nut flavors. Technically it has a POD of 0 (no sweetness) and a very high PAC of 585, about 5.85 times sucrose, so even a fraction of a gram measurably depresses the freezing point and softens texture. Because the usable amount is capped by taste, its real contribution to total mix PAC stays small; treat it as a seasoning, not a freezing-point tool. Add it dissolved into the liquid phase so it disperses evenly.
Origin & background
Salt's link to frozen desserts is centuries old: long before mechanical freezers, ice cream was churned in a bath of ice mixed with salt, an endothermic mixture that can drop to roughly -21 C, cold enough to freeze the mix. That ice-and-salt technique was documented in Europe by the 16th-17th centuries. Using salt inside the mix itself, as a seasoning rather than a coolant, is a modern refinement popularised by salted-caramel and gastronomic gelato.
