This is inspired by Kingdom Hearts ;D Recipe can be found all over the internet.
You'll need: Sea salt, 2 cups milk, 1 teaspoon vanilla (or vanilla extract), 1/3 cup sugar, 2 eggs, 1 cup heavy whipping cream, blue food coloring, and green food coloring.
Directions:Separate the egg whites from the egg yolks in two different bowls.
Whisk the egg whites and add the sugar to the egg yolks. Beat until mixed together good.
In a medium sauce pan put the milk on the stove. Put on medium heat (be careful. Watch the milk!) and let it lightly boil.
Take it off and put it in the egg yolk/sugar mixture, then put back into the medium sauce pan. Don't let the milk boil. Stir until the mixture thickens like custard.
Then pour custard into the egg whites and mix well. Add the sea salt. It all depends on how salty you want the ice cream to be but the right thing is to have it mixed well with the sweetness of the sugar.
Refrigerate till it gets cool. Take it out add the cream and vanilla.
Then add 3 drops of green food coloring. Mix and then add 12-13 drops of blue food coloring.
Pour either into a metal pan or into ice cream molds. Let it freeze for about 8 hours or so.
Should look like this:
