Blend the raspberries:
In a blender, combine raspberries, milk, honey (or maple syrup), vanilla, and salt. Blend until smooth and creamy.
Mix with chia seeds:
Pour the raspberry mixture into a large bowl or jar. Add the chia seeds and stir well to combine.
Let it thicken:
Cover and refrigerate for at least 4 hours or overnight. Stir once after the first 15 minutes to prevent chia clumps.
Serve:
Give the pudding a final stir before serving. Spoon into individual jars or bowls and top with your favorite add-ons like yogurt, berries, granola, or coconut flakes.
