This simple recipe uses just four ingredients, but it does require planning ahead.
To do this you really need to make the ice cream a day ahead and then expect an hour in the ice cream maker whule it freezes.
1 cup milk
1 cur heavy cream
1/4 cup sugar
2 tbsp vanilla flavoring
On the day before...
Combine the four ingredients in a sauce pan and warm over low heat, wisking consistently. You don't want the mixture to boil because it will quickly bubble over and make a mess all over your stove. Just be patient and allow it to simmer with a low roll for about five minutes.
After cooking, allow the cream mixture to cool, then transfer it a container and refrigerate it -- overnight if possible. At the same time, place the cream container from the ice cream machine into the freezer, and leave it overnight, too.
When ready to make the ice cream...
When ready to make the ice cream, remove the cream mixture from the fridge and the container from the freezer, and pour the cream mixture into the chilled container. Place it into the ice cream maker, and pack ice around the edges. Add some rock salt or sea salt into the ice, which will hasten the the melting and allow the water to be a temoerature lower than normal frrzing point (32°F / 0°C).
Allow the mixer to churn for an hour. Check progress as the time nears, and adjust timing in either direction as necessary.
