Refrigerate the yogurt, granola, and fruits separately for at least 2 hours before assembling to ensure each layer stays distinct and maintains optimal texture and flavor contrast.

Gently peel rambutans by making a shallow cut around the crown and twisting to reveal the translucent flesh, then chill immediately to prevent browning and maintain their delicate sweetness.

Add granola only 5-10 minutes before serving to prevent it from absorbing moisture and losing its crunch, which is essential for textural contrast in each spoonful.

Dice papaya and mango separately and add them just before serving, as their natural enzymes can break down dairy-free yogurt's protein structure if left sitting too long.

Alternate thin layers starting and ending with yogurt, using taller glasses to showcase the colorful fruits; this technique maximizes visual appeal and allows flavors to meld harmoniously.
