In a bowl or in a mason jar, combine chia seeds with milk, a pinch of salt, and optionally maple syrup. Give it a good mix with a spoon, or close the jar and shake well.
Let the mixture rest for 5-10 minutes, preferably in the refrigerator.
Use a spoon or fork to stir the pudding from bottom up. This step is necessary to break any clump of chia seeds that may have formed at the bottom.
Close the jar with lid or cover the bowl with plastic wrap and refrigerate for at least 2 hours or overnight, until the chia seeds have thickened into a pudding.
Give it a stir, the serve with your favorite toppings.
