I posted this in a thread on the green coffee coop along with another chocolate chip version. But, you have to be a member of the Co-op to access the thread, but joining is free.
Ok, I think I finally have a working recipe for those that were interested.
You will need...
1 ½ cups 2% milk
Coffee
¾ cup sugar
¼ teaspoon salt
3 egg yolks, beaten
½ tablespoon vanilla
2 cups ice cold whipping cream
The hard part was getting the coffee flavor. If you use espresso, it gets bitter, if you use coffee brewed in water, there is not enough cream in the mix and you end up with a block of ice. While not good for ice-cream, break it into chunks toss it in a blender with a little milk and you have a coffee milkshake.
Take one and a half cups of 2% milk and heat it just short of a boil, 198'ish F.
While the milk is heating, put the appropriate amount of coffee into your French press. Once the milk is at temperature, dump it into the press pot and let steep one minute longer than you normally do. Press and pour the milk pack into your pan. You should have one cup of coffee infused milk after the press.
Whip 3 egg yolks; slowly add one quarter of the hot milk to the egg yolk (tempering the eggs). Keep whipping the eggs while you add the milk. Then add the egg and milk mix back to the pan. Add in three-quarter cup sugar, one-quarter teaspoon salt and cook on medium heat stirring constantly until thickened. You are making loose custard. The mix should coat the back of a spoon.
Refrigerate the mix overnight.
Just before churning, mix in one half tablespoon vanilla and two cups of ice cold whipping cream (heavy cream, 30%+ milk fat). Hay, I said it was good, not low calorie. Don't even try half and half. Low fat ice-cream is like decaf coffee, why bother?
Mix well and churn in your ice-cream maker, freeze a few hours to harden and enjoy.
