Italian gelato

Denser and more intense: less fat and air, more milk, served warmer.

In Italian, “gelato” simply means any ice cream. Outside Italy the word refers to the Italian artisan style: ice cream with less fat, less air and more milk than classic cream ice cream, served warmer. The result is dense and elastic, and the flavour is more pronounced — fat does not mute it, and the ice cream does not numb your tongue the way it does at −18 °C.

Gelato is traditionally made on a milk base (fior di latte, pistachio, hazelnut, chocolate), or with egg yolks as “crema”. Fruit gelato is made with water or with milk, and pure fruit gelato comes close to sorbet.

Origin and history

The birth of gelato is often linked to 16th-century Florence and names such as Bernardo Buontalenti or Ruggeri. These stories, however, are at least partly legend and are not reliably documented. What is more certain is that the Italian Francesco Procopio dei Coltelli opened the Café Procope in Paris, recorded from 1686 and associated with the spread of Italian frozen desserts in France. Modern artisan gelato owes a great deal to machines: the Bologna company Carpigiani began selling an ice cream machine in 1945.

Typical composition

The figures for gelato come mainly from the English and Italian Wikipedia and from practice, not from a standard — treat them as a guide. There is no verified exact range for MSNF.

For comparison: according to Italian sources, industrial ice cream used to have an overrun of 70–130 %. Milk usually makes up at least 60 % of a gelato recipe, cream 5–20 %.

Gelato often uses several kinds of sugar at once: besides sucrose also dextrose or invert sugar. These lower the freezing point more than ordinary sugar, so gelato stays soft even with less fat. The explanation and a table of coefficients are in the article PAC and POD.

What the law says

Italian figures such as “at least 32 % solids” or “18 % sugars in fruit gelato” are often quoted, but their origin in Italian regulations could not be verified.

How to make it at home

The method is similar to cream ice cream, just with a different ratio of ingredients:

1. Base. Milk, less cream, skimmed milk powder (adds protein and solids without fat), sugar and dextrose. Mix the stabiliser with the sugar so it does not form lumps.
2. Heating. Heat the base and hold it at pasteurisation temperature; artisan producers quote around 85 °C, followed by rapid cooling to 5 °C.
3. Ageing. At least 4 hours in the fridge.
4. Churning. In the machine until it is thick and matt.
5. Hardening. Only briefly, 1–2 hours, then serve.

Gelato is balanced for display cabinet temperature (around −12 °C). In a home freezer at −18 °C it gets harder, so:

• eat it fresh, ideally on the day it is made,
• let it sit in the fridge for 10–15 minutes before serving,
• if you want to store it, increase the share of dextrose in the recipe — the app shows the PAC of the mix.

Equipment: a compressor ice cream maker, a freezer-bowl ice cream maker or a Ninja CREAMi. Professional shops use batch freezers.

Recipes: fior di latte, pistachio gelato, crema with egg yolks and water-based chocolate gelato.

The most common mistakes

• Rock-hard from the freezer — gelato balanced for −12 °C is not built for −18 °C. The fix is tempering it or adding more dextrose.
• Icy — too few solids at low fat, no stabiliser or milk powder, the base was not aged.
• Sandy — too much milk powder; the lactose crystallises.
• Bland flavour — gelato stands or falls on its ingredients. Cheap pistachio paste or flavouring has nowhere to hide in a dense, low-fat ice cream.
• Gummy — too much stabiliser or starch.

How to recognise good gelato

The gelato equipment maker Frigomeccanica and food hygiene inspectors advise looking for:

• natural, muted colours — pistachio is olive to brownish green, banana beige to greyish, lemon almost white,
• low mounds — tall, sculpted “mountains” of ice cream hold their shape thanks to additives and a lot of air,
• covered tubs (pozzetti) — they protect the gelato from heat and light,
• a dense, compact texture without crystals,
• a seasonal selection and an understandable list of ingredients.

How long it takes at home

Total: about 40 minutes of active work, from 6 hours to a day in all.
