FormulaMapsPAC and POD are theoretical indices. The freezing curve is physical reality: how your gelato behaves between the hardening cabinet (−25 °C) and the display case, and, above all, how it will feel on the spoon.
What it shows, exactly
For any given recipe, the freezing curve maps temperature against the percentage of water that has frozen. From that graph you can read four key things:
| Concept | What it tells you |
|---|---|
| Initial freezing temperature | The temperature at which the first ice crystal begins to form. |
| Ideal serving temperature | The temperature at which to serve the gelato so it scoops perfectly. |
| % frozen water | How much of your free water has turned to ice at each temperature point. |
| Estimated hardness | How the texture will feel: soft, creamy, plastic, or hard. |
How to read it
- The leftmost point on the curve shows where freezing begins.
- The serving-temperature point shows where you pull it from the case and it scoops just right.
- A widely used industry benchmark places the ideal scoopable point at around 62 % frozen water.
- The lower the temperature, the more water turns to ice and the harder the texture becomes.
The key takeaway
A recipe can have PAC and POD perfectly "in range" and still come out like a brick — or far too soft. The freezing curve reveals this before you churn, not after.
Two problems you can only see with the curve
1. Gelato that's too soft
If you've overdone the dextrose or invert sugar, the initial freezing temperature drops sharply and, at a normal display-case temperature, too much water remains unfrozen. The curve shows this clearly: reduce those sugars and watch the curve shift until the serving point lands at a workable display temperature.
2. Sorbet that sets like concrete
A sorbet with too little sugar freezes almost all its water very quickly. By −18 °C, the bulk of the water has already turned to ice. The curve flags the problem, and when you raise the sugar content — typically dextrose, to avoid oversweetening — you can see the slope become more gradual until the product is scoopable at display-case temperature.
Why it matters for your business
The freezing curve connects your formula to two very practical decisions: what temperature to set the display case at and what the gelato feels like to the customer. Getting that right means less wasted product, a consistent texture, and a display case that performs just as well at opening time as it does at the end of the day.
