Whisk the base: In a medium bowl, whisk coconut milk until smooth (some cans separate—no big deal). Add maple syrup, vanilla, and sea salt.
Add the chia: Sprinkle chia seeds over the liquid and whisk thoroughly for 30–45 seconds to prevent clumps.
Rest, then whisk again: Let the mixture sit for 10 minutes. Whisk again to break up any sneaky clumps. This step is the secret to silky texture.
Chill to set: Cover and refrigerate for at least 2 hours, ideally 4 hours or overnight, until thick and pudding-like.
Adjust thickness: If it’s too thick, stir in 1–3 tablespoons coconut milk or any milk. Too thin? Add 1–2 teaspoons chia, stir, and chill 15–30 minutes.
Serve and top: Spoon into bowls or jars. Add fruit, nuts, toasted coconut, and a squeeze of lime if you’re feeling fancy.
