Storage: The chia pudding base keeps in an airtight container in the refrigerator for up to 5 days. Assembled parfaits are best eaten within 24 hours. Store toasted coconut flakes separately at room temperature and add just before serving to preserve crunch. Chia seed ratio: Use 3 tablespoons chia seeds per 1 cup of liquid for a thick, spoonable pudding. Reduce to 2.5 tablespoons per cup for a looser consistency, or increase to 3.5 tablespoons for a very firm set. Protein boost: Stir 1 scoop of vanilla protein powder into the coconut milk base before adding chia seeds. Fruit swaps: Sliced kiwi, papaya, passion fruit pulp, or fresh berries all work beautifully in place of or alongside the mango and pineapple.
