Gather your tools: You’ll need a small mixing bowl, a whisk or fork, and a jar or container with a lid.
Mix the base: In the bowl, whisk together 1 cup milk, 1–2 tablespoons maple syrup (to taste), 1–2 teaspoons finely grated lemon zest, 1 tablespoon fresh lemon juice, 1/2 teaspoon vanilla extract, and a pinch of salt.
Add chia seeds: Whisk in 3 tablespoons chia seeds. Whisk for 30–45 seconds to distribute evenly and prevent clumps.
Rest and re-whisk: Let the mixture sit for 5–10 minutes, then whisk again. This step is key for a smooth, even texture.
Chill: Transfer to a jar or keep it in the bowl.
Cover and refrigerate for at least 2–3 hours, or overnight for best results.
Stir and taste: Once set, give it a good stir. If it feels too thick, add a splash of milk. Adjust sweetness or lemon to taste.
Serve: Spoon into bowls and top with fresh berries, a dollop of yogurt, or a sprinkle of coconut and extra zest.
