Blend the coconut milk (except the ¼ cup reserved), ¼ cup honey, the coconut sugar, and 1 teaspoon of salt in a blender until combined.
Heat over medium heat. While the ice cream base is heating up, whisk the starch and ¼ cup reserved coconut milk together in a small bowl. Once the base has warmed, add the starch mixture and whisk occasionally until the mixture has thickened. You'll find it starts to thicken on the bottom and edges of the pan first and will coat the back of a spoon. You may get some small bubbles, but don't let it boil.
Remove from heat and stir in the vanilla extract. Pour into a glass dish and place in the fridge, whisking every 30 minutes until completely cooled (about 2 hours).
Once your base has cooled, transfer to ice cream maker per manufacturers directions. I have this Cuisinart ice cream maker and it takes about 15 minutes for the ice cream to finish churning.
Once done churning, transfer half of the ice cream into your freezer safe dish. Drizzle with 1 tbs of honey and ½-1 teaspoon of salt and use a knife to marble it into the ice cream. Top with the remaining ice cream and complete the same process with the last tablespoon of honey and another ½-1 teaspoon of salt.
Freeze for several hours to harden completely and remove about 10+ minutes before serving to soften slightly. Enjoy!
