Subtle House's Cookbook

Note: If you can't get coconut cream, substitute 5 oz creamed coconut (the very condensed dehydrated coconut that comes in a box) and 10 oz hot water. DO NOT use anything labeled "cream of coconut"--that's sweetened stuff for use in mixed drinks.

Note: In addition to adding flavor, liquor will help the ice cream form smaller ice crystals for a smoother texture. You can leave it out if you're serving the ice cream to people who strictly abstain from alcohol.

Ingredients

1 13.5-oz can full-fat coconut milk (not anything labeled "light" or "low-fat")
1 14-oz can coconut cream
0.25 c "light" (clear) corn syrup
0.75 c sugar
2 tsp vanilla extract (optional)
1 Tbsp liquor, such as vodka, rum, or whiskey (optional)
0.5 tsp salt
1.25 c mix-ins, if desired (sweetened shredded coconut, chocolate chips, toasted almonds--whatever you want to add)

Equipment

Can opener (if needed)
Measuring cups and spoons
2-quart pot
Spatula
Stove (1 burner)
Blender or immersion blender (don't use an immersion blender with a nonstick pot!)
2 freezer-safe airtight pint (2-cup) containers (glass jars and old Talenti containers are both great for this)
Refrigerator
Freezer
Ice cream maker

Instructions

0) Mise en place. Gather your ingredients and tools. Put the ice cream maker bowl in the freezer if it's not there already.

1) Make the custard. Combine the coconut milk, coconut cream (or creamed coconut and hot water), corn syrup, and sugar in the nonstick pot. Cook over medium heat, stirring often with the spatula, until the mixture comes to a simmer and the solid coconut oil has completely dissolved. Transfer the mixture to the blender and cover tightly and securely, or use the immersion blender in the pot. Blend on high speed for 1 minute to emulsify any last grainy bits of coconut oil. Return to the pot and stir in the vanilla extract and liquor (if using). Add salt to taste. Pour the custard into the pint containers, cool to room temp with the lids slightly ajar, close the lids tightly, and refrigerate about 4 hours or until the liquid temperature is at or below 45F.

2) Make the ice cream. Make sure the ice cream maker bowl is frozen solid (shake it to test--you shouldn't hear or feel any sloshing) and the custard is thoroughly chilled. If the custard has separated, shake the jars briefly to reconstitute it. Place the bowl in the ice cream maker, put in the stirrer, and put on the lid. Start the machine and immediately pour in all the custard. Set a timer for 20 minutes. Put your add-ins in the freezer to chill (unless you're planning to melt the chocolate for straciatella). After 20 minutes, or when the ice cream has thickened to the texture of a milkshake, gradually add the add-ins, making sure the ice cream isn't overflowing the ice cream maker. Churn an additional 5 minutes or until add-ins are thoroughly incorporated. Stop the machine and scrape the ice cream into the pint containers. Freeze 5 hours or until solid and scoopable.
