Start with the liquid base: In a medium bowl or jar, whisk together the plant-based milk, lemon zest, lemon juice, vanilla, sweetener, and a pinch of salt. Taste and adjust sweetness or lemon to your liking.
The base should taste slightly sweeter than you want the final pudding to be.
Add chia seeds slowly: Sprinkle the chia seeds over the liquid while whisking. This helps prevent clumps. Aim for about 6 tablespoons of chia for 2 cups of liquid as a starting point.
Whisk well, then wait: Let the mixture rest for 5 minutes, then whisk again to break up any seeds sticking together.
This second whisk is key for an even, creamy texture.
Chill to set: Cover and refrigerate for at least 2–3 hours, or overnight for best results. The pudding will thicken as the chia absorbs the liquid.
Check consistency: Stir after chilling. If it’s too thin, add 1–2 teaspoons more chia, whisk, and chill another 20–30 minutes.
If it’s too thick, stir in a splash of milk until it’s just right.
Serve and top: Spoon into bowls or jars and add your favorite toppings. Fresh berries and a little extra lemon zest are especially good here.
