You don't need to peel the fruit, the skin is edible and rich in nutrients. But cut open the fruit and take out and discard the seeds.
Place sapodilla fruit pieces into a blender jar with the milk. You can add sugar if you like, I don't.
2 Sapodilla, 1 cup Milk, Sugar
You can add crushed ice to make a thick milkshake (reduce milk quantity by a ⅓). Alternativly, you can also use frozen sapodilla fruit pieces.
Crushed Ice
Blend to a smooth milkshake. If you left the skin on the fruit, you might get some tiny pieces in your milkshake. I like it because it adds texture.
Serve up cooled.
Notes
You can use regular animal milk or plant-based milks such as soy milk, oat milk, rice milk, cashew milk, coconut milk, pecan milk to just name a few.
Adding sugar is optional, and I, personally, skip it because the fruits are sweet enough. You can add regular sugar, or sugar alternatives such as panela, jaggery, brown sugar, dates, monk sugar, stevia.
Ice is optional, but can make the smoothie even thicker in consistency.
