Peel the banana and slice it into smaller pieces so it blends easily. If using fresh turmeric or ginger, grate them finely using a microplane grater. Measure the frozen mango chunks and yogurt so everything is ready before blending.

Pour the coconut milk into the blender first. Then add the yogurt, banana slices, frozen mango chunks, grated turmeric, cardamom, ginger, and lemon juice. Placing liquid ingredients at the bottom helps the blender process frozen fruit smoothly.

Blend on high speed for about 45–60 seconds until the mixture becomes completely smooth and creamy. The smoothie should have a bright golden color and thick texture. If the smoothie feels too thick, add a splash of coconut milk and blend again.

Pour the smoothie into tall glasses. Sprinkle shredded coconut or a pinch of turmeric on top for garnish. Serve immediately while chilled and creamy.
