Well, this is a really weird way to make ice cream but would be interesting to try. Found it via Reddit.
Ingredients
1 1/2 Cups Whole Milk
1/2 Cup Heavy Whipping Cream
1/2 Cup Coffee - Room Temperature
1 oz Irish Whiskey
1 tsp Vanilla Extract
4 Large Egg Yolks
1/2 Cup Brown Sugar
Pinch Maldon Smoked Salt
Instructions
1. Set up Nomiku water bath and turn temperature to 85ºC (185ºF). In a large mixing bowl, whisk together egg yolks, milk, heavy cream, coffee, sugar, vanilla, and whiskey. Pour into a freezer-safe zip bag. Seal bag using the water displacement method and submerge in water bath to sous vide for 1 hour.
2. Remove ice cream mixture from water bath. The alcohol will have separated from the cream so give the bag a good shake until everything is uniform again. Place bag into a cold ice bath until the mixture has completely cooled.
3. Freeze the mixture in an ice cream maker according to instructions or use our special hack (http://bit.ly/sous-vide-ice-cream) Add a pinch of smoked salt into the ice cream maker in the last few minutes of churning. Pack into freezer container and cover the top of the ice cream with plastic wrap. Freeze for at least a couple hours.
4. If using our hack, garnish lightly with smoked salt upon serving.
