-
Whisk together eggs, sugar, condensed milk, and salt until thick and smooth in a very large heatproof bowl.
-
Heat 2 cups of the cream with the regular milk, bringing this to a full rolling boil.
-
Slowly pour some of the hot mixture into the egg mixture, whisking constantly to mix in quickly so the eggs do not scramble.
-
Add the rest of the milk mixture slowly, still whisking fiercely, and mix to combine.
-
Return entire mixture back to the pan and cook, stirring with a wooden spoon, until the mxiture thickens slightly and a finger drawn down the back of the spoon leaves a clear line.
-
Strain mixture through a mesh strainer over a large bowl.
-
Whisk in coffee crystals until dissolved.
-
Add vanilla and the remaining cream.
-
Chill in fridge until very cold.
-
Freeze in an ice cream maker according to manufacturer's instructions.
-
NOTE: Once your freezing cycle has completed on your machine, the consistency may be soft- you may wish to ripen the ice cream by storing it in an airtight container in your regular freezer until firm; this will especially be the case when using smaller capacity electric machines.
