• First need to prepare a good strong coffee. Do not sugar it; the coffee should be bitter. Also, the coffee must be ristretto, that means short, concentrated, with an intense flavor.
• WITH ESPRESSO MACHINE: To reach the dose given in the recipe, you need to prepare 3 ristretto coffees with the espresso machine (one ristretto coffee is about 40 ml/2.7 tablespoons).
• WITH MOKA: If using the traditional Moka, use the 3-dose coffee Moka. Press the coffee well and keep the water level just below the valve.
• In a bowl, mix the egg yolks with the sugar. Beat with a whisk, preferably electric, until the mixture is thick and fluffy.
• Meanwhile, pour the milk into a saucepan and bring it almost to a boil. Cook for about 5 minutes. The milk must NOT boil. If you have a kitchen thermometer you can check that the temperature remains at about 85°C (185°F). If you don't have a thermometer, take care to remove the saucepan from the heat if you see that the milk starts to boil.
• Add the coffee to the hot milk.
• Then transfer the soft cream of eggs and sugar to a saucepan. Finally, slowly pour in the hot milk with coffee while keeping stirring. In this way you are pasteurizing the eggs.
• Put it back on the heat and cook for another 5 minutes, without boiling and always stirring
• Then turn off the heat and add the cold heavy cream. Mix really well. The mixture for coffee gelato is ready!
