Measure out the frozen pineapple and mango chunks, transferring them into the blender.
1 cup frozen pineapple chunks, 1 cup frozen mango chunks
Add the coconut milk to the blender, pouring directly over the frozen fruit.
1 cup coconut milk
Add honey for extra sweetness, if desired. Secure the lid tightly on the blender.
1 tbsp honey
Blend on high speed until the mixture becomes smooth and creamy, with a thick, slightly frosty texture. Observe the color brighten as ingredients combine, and listen for the sound of the motor running steadily.
Stop the blender and check the consistency; if the smoothie is too thick, add a splash more coconut milk and blend briefly until smooth. The final result should be thick, icy, and well combined, ready to serve.
Pour the smoothie into glasses, and optionally garnish with fresh fruit or a slice of pineapple for presentation.
