*This recipe as tested does require an ice cream churner, but the base is so thick and creamy that I think you can get away with just freezing the base (not churned) and then stirring/whisking every hour to incorporate air until firm.
*You can sub light coconut milk but with less creamy results.
*I do not recommend trying to substitute maple syrup, coconut sugar, or agave for the cane sugar in this recipe. It will affect the flavor and texture negatively. Cane sugar or even corn syrup (not high fructose) are best. The only potential alternative I would recommend would be subbing up to half the amount of sugar with corn syrup or honey (which would make this recipe not vegan-friendly).
