Whisk the liquids: In a medium bowl, whisk the almond milk, coconut milk, sweetener, lemon juice, vanilla, and salt until smooth and the sweetener dissolves. Taste and adjust sweetness.
Add zest and chia: Stir in the lemon zest, then sprinkle the chia seeds on top. Whisk well to distribute the seeds evenly so they don’t clump.
Rest and whisk again: Let the mixture sit for 5–10 minutes, then whisk again.
This second whisk prevents clumps and ensures a smooth pudding.
Chill: Cover and refrigerate for at least 2 hours, or overnight for a thicker texture. The chia seeds will absorb the liquid and create a custard-like consistency.
Stir and serve: Give the pudding a final stir. If it’s too thick, loosen with a splash of almond milk.
If it’s too thin, add 1–2 teaspoons more chia seeds and chill 30 minutes longer.
Finish with toppings: Spoon into jars or bowls and add your choice of toppings. A little extra lemon zest or a few berries adds color and brightness.
