Notes
Ube ice cream remains slightly softer than my other no churn ice cream recipes on the blog therefore it can be served immediately it comes out of the refrigerator.
Ube ice cream is very tasty. Don't be tempted to add more than 1 Tbsp of ube extract to this recipe except you are doubling the recipe. (While recipe testing I found the extract to leave an aftertaste when a lot is added.)
