Toast the coconut flakes: Place a dry skillet over medium heat and add the coconut flakes. Stir constantly for 2–4 minutes until they are golden and fragrant. Why: Toasting coconut intensifies its nutty aroma and adds crunchy texture — don’t walk away because coconut can burn quickly. Transfer to a plate to stop the cooking.

Make the mango puree: If using fresh mango, peel and dice about 1 large mango (≈225 g). If using frozen, thaw and drain excess water. Purée the mango in a blender or food processor until smooth (leave a few small bits if you like texture). Why: A smooth mango purée integrates beautifully with the pudding and creates a vibrant layer; small mango bits will give pleasant bursts of fruit.

Combine the wet ingredients: In a large mixing bowl, whisk together the unsweetened coconut milk, vanilla extract, maple syrup (if using), and a pinch of salt. Why: Dissolving the sweetener and evenly distributing the vanilla in the liquid before adding chia prevents uneven sweetness and helps the seeds hydrate evenly.

Add the chia seeds: Pour the chia seeds into the coconut-milk mixture and stir vigorously for 20–30 seconds so the seeds don’t clump. Why: Chia seeds can form gelatinous clumps if not stirred immediately; a vigorous stir disperses them so each seed hydrates and swells uniformly.

Initial rest and re-stir: Let the mixture sit at room temperature for 10 minutes, then stir again, breaking up any clumps. Why: Chia begins to absorb liquid quickly; a second stir after initial swelling ensures a smooth texture rather than a lumpy pudding.

Portion and layer (optional): For pretty presentation, spoon about two-thirds of the chia pudding into 4 serving jars or bowls. Add a layer (about 2–3 tbsp) of mango purée, then finish with the remaining chia mixture, or simply swirl the mango through the top layer. Why: Layering creates a restaurant-quality look and guarantees a balanced bite of fruit and pudding every time.

Chill: Cover the jars or bowl with plastic wrap or lids and refrigerate for at least 4 hours or overnight to fully set. Why: Chia seeds continue to hydrate as they chill; a minimum of 4 hours ensures a creamy, pudding-like consistency. Overnight makes it even silkier.

Finish and serve: Before serving, top each jar with toasted coconut flakes and fresh mango cubes. If the pudding is very thick after chilling, stir in 1–2 tbsp of coconut milk to loosen. Why: The toasted coconut adds crunch and aroma; a small splash of milk refreshes texture without diluting flavor.

Storage: Keep covered in the refrigerator for up to 4 days. If keeping longer, add toasted coconut just before serving to avoid sogginess. Why: Chia pudding holds well, but toppings like toasted coconut lose their crispness if stored assembled for too long.
