This frosty drink combines unsweetened coconut milk with pineapple extract and shredded coconut to create a thick, tropical consistency. It has a creamy and sweet flavor profile as a sugar-free chilled drink that can be made with or without alcohol.
About This Recipe
To create the base, coconut milk is blended with ice and pineapple extract until the mixture reaches a smooth, slush-like texture. Using pineapple extract instead of juice allows for a concentrated tropical taste while keeping the sugar content low. It is important to blend the ingredients on high speed to fully incorporate the shredded coconut and any frozen additions, ensuring the final drink is consistent and free of large ice chunks.
The flavor relies on the richness of the coconut milk, which gives a creamy mouthfeel that balances the acidity of the pineapple flavoring. Powdered sweetener is added to match the sweetness of a traditional cocktail without the grittiness of granulated sugar. The addition of frozen zucchini or strawberries is used to provide body and thickness to the smoothie without significantly altering the primary coconut and pineapple profile.
This smoothie suits a light drink or dessert and can be made in under five minutes. It’s easy to customize by adding a scoop of vanilla protein powder for a more substantial drink or a splash of rum for a classic cocktail version. It is best served immediately in a chilled glass, garnished with extra shredded coconut to enhance the tropical aroma.
